nilfs2: add /sys/fs/nilfs2/<device> group
This patch adds creation of /sys/fs/nilfs2/<device> group. The <device> group contains attributes that describe file system partition's details: (1) revision - show NILFS file system revision. (2) blocksize - show volume block size in bytes. (3) device_size - show volume size in bytes. (4) free_blocks - show count of free blocks on volume. (5) uuid - show volume's UUID. (6) volume_name - show volume's name.

nilfs2: add /sys/fs/nilfs2/features group
This patchset implements creation of sysfs groups and attributes with the purpose to show NILFS2 volume details, internal state of the driver and to manage internal state of NILFS2 driver. Sysfs is a virtual file system that exports information about devices and drivers from the kernel device model to user space, and is also used for configuration. NILFS2 is a complex file system that has segctor thread, GC thread, checkpoint/snapshot model and so on. Sysfs namespace provides native and easy way for: (1) getting info and statistics about volume state; (2) getting info and configuration of internal subsystems (segctor thread); (3) snapshots management. Suggested patchset provides basis for managing segctor thread behaviour and manipulation by snapshots. Currently, it informs only about segctor thread's internal parameters and about mounted snapshots. But sysfs interface can provide easy and simple way for deep management of segctor thread and snapshots. This patchset provides opportunity to manage interval of periodical update of superblock (in seconds). Default value is 10 seconds. Now a user can increase this value by means of nilfs2/<device>/superblock/sb_update_frequency attribute in the case of necessity. Also the patchset provides opportunity to get information easily about key volumes's parameters (free blocks, superblock write count, superblock update frequency, latest segment info, dirty data blocks count, count of clean segments, count of dirty segments and so on) in real time manner. Such information can be used in scripts for subtle management of filesystem. Implemented functionality creates such groups: (1) /sys/fs/nilfs2 - root group (2) /sys/fs/nilfs2/features - group contains attributes that describe NILFS file system driver features (3) /sys/fs/nilfs2/<device> - group contains attributes that describe file system partition's details (4) /sys/fs/nilfs2/<device>/superblock - group contains attributes that describe superblock's details (5) /sys/fs/nilfs2/<device>/segctor - group contains attributes that describe segctor thread activity details (6) /sys/fs/nilfs2/<device>/segments - group contains attributes that describe details about volume's segments (7) /sys/fs/nilfs2/<device>/checkpoints - group contains attributes that describe details about volume's checkpoints (8) /sys/fs/nilfs2/<device>/mounted_snapshots - group contains group for every mounted snapshot (9) /sys/fs/nilfs2/<device>/mounted_snapshots/<snapshot> - group contains details about mounted snapshot This patch (of 9): This patch adds code of creation /sys/fs/nilfs2 group and /sys/fs/nilfs2/features group. The features group contains attributes that describe NILFS file system driver features: (1) revision - show current revision of NILFS file system driver. There are two formats of timestamp output - seconds and human-readable format. Every showed timestamp has two sysfs files (time-<xxx> and time-<xxx>-secs). One sysfs file (time-<xxx>) shows time in human-readable format. Another sysfs file (time-<xxx>-secs) shows time in seconds. It was reported by Michael Semon that timestamp output in human-readable format should be changed from "2014-4-12 14:5:38" to "2014-04-12 14:05:38". Second version of the patch fixes this issue.

mm: memcontrol: rewrite uncharge API
The memcg uncharging code that is involved towards the end of a page's lifetime - truncation, reclaim, swapout, migration - is impressively complicated and fragile. Because anonymous and file pages were always charged before they had their page->mapping established, uncharges had to happen when the page type could still be known from the context; as in unmap for anonymous, page cache removal for file and shmem pages, and swap cache truncation for swap pages. However, these operations happen well before the page is actually freed, and so a lot of synchronization is necessary: - Charging, uncharging, page migration, and charge migration all need to take a per-page bit spinlock as they could race with uncharging. - Swap cache truncation happens during both swap-in and swap-out, and possibly repeatedly before the page is actually freed. This means that the memcg swapout code is called from many contexts that make no sense and it has to figure out the direction from page state to make sure memory and memory+swap are always correctly charged. - On page migration, the old page might be unmapped but then reused, so memcg code has to prevent untimely uncharging in that case. Because this code - which should be a simple charge transfer - is so special-cased, it is not reusable for replace_page_cache(). But now that charged pages always have a page->mapping, introduce mem_cgroup_uncharge(), which is called after the final put_page(), when we know for sure that nobody is looking at the page anymore. For page migration, introduce mem_cgroup_migrate(), which is called after the migration is successful and the new page is fully rmapped. Because the old page is no longer uncharged after migration, prevent double charges by decoupling the page's memcg association (PCG_USED and pc->mem_cgroup) from the page holding an actual charge. The new bits PCG_MEM and PCG_MEMSW represent the respective charges and are transferred to the new page during migration. mem_cgroup_migrate() is suitable for replace_page_cache() as well, which gets rid of mem_cgroup_replace_page_cache(). However, care needs to be taken because both the source and the target page can already be charged and on the LRU when fuse is splicing: grab the page lock on the charge moving side to prevent changing pc->mem_cgroup of a page under migration. Also, the lruvecs of both pages change as we uncharge the old and charge the new during migration, and putback may race with us, so grab the lru lock and isolate the pages iff on LRU to prevent races and ensure the pages are on the right lruvec afterward. Swap accounting is massively simplified: because the page is no longer uncharged as early as swap cache deletion, a new mem_cgroup_swapout() can transfer the page's memory+swap charge (PCG_MEMSW) to the swap entry before the final put_page() in page reclaim. Finally, page_cgroup changes are now protected by whatever protection the page itself offers: anonymous pages are charged under the page table lock, whereas page cache insertions, swapin, and migration hold the page lock. Uncharging happens under full exclusion with no outstanding references. Charging and uncharging also ensure that the page is off-LRU, which serializes against charge migration. Remove the very costly page_cgroup lock and set pc->flags non-atomically.

mm: memcontrol: rewrite charge API
These patches rework memcg charge lifetime to integrate more naturally
with the lifetime of user pages. This drastically simplifies the code and
reduces charging and uncharging overhead. The most expensive part of
charging and uncharging is the page_cgroup bit spinlock, which is removed
entirely after this series.
Here are the top-10 profile entries of a stress test that reads a 128G
sparse file on a freshly booted box, without even a dedicated cgroup (i.e.
executing in the root memcg). Before:
15.36% cat [kernel.kallsyms] [k] copy_user_generic_string
13.31% cat [kernel.kallsyms] [k] memset
11.48% cat [kernel.kallsyms] [k] do_mpage_readpage
4.23% cat [kernel.kallsyms] [k] get_page_from_freelist
2.38% cat [kernel.kallsyms] [k] put_page
2.32% cat [kernel.kallsyms] [k] __mem_cgroup_commit_charge

1.39% kswapd0 [kernel.kallsyms] [k] free_pcppages_bulk
1.30% cat [kernel.kallsyms] [k] kfree
As you can see, the memcg footprint has shrunk quite a bit.

This patch (of 4):
The memcg charge API charges pages before they are rmapped - i.e. have an
actual "type" - and so every callsite needs its own set of charge and
uncharge functions to know what type is being operated on. Worse,
uncharge has to happen from a context that is still type-specific, rather
than at the end of the page's lifetime with exclusive access, and so
requires a lot of synchronization.
Rewrite the charge API to provide a generic set of try_charge(),
commit_charge() and cancel_charge() transaction operations, much like
what's currently done for swap-in:
mem_cgroup_try_charge() attempts to reserve a charge, reclaiming
pages from the memcg if necessary.
mem_cgroup_commit_charge() commits the page to the charge once it
has a valid page->mapping and PageAnon() reliably tells the type.
mem_cgroup_cancel_charge() aborts the transaction.
This reduces the charge API and enables subsequent patches to
drastically simplify uncharging.
As pages need to be committed after rmap is established but before they
are added to the LRU, page_add_new_anon_rmap() must stop doing LRU
additions again. Revive lru_cache_add_active_or_unevictable().

to store memory bitmaps which should speed up some operations carried
out by it quite significantly. We also have some power management
changes related to suspend-to-idle (the "freeze" sleep state) support
and more preliminary changes needed to support ACPI on ARM (outside of
ACPICA).
The rest is fixes and cleanups pretty much everywhere.
Specifics:
- ACPICA update to upstream version 20140724. That includes ACPI 5.1
material (support for the _CCA and _DSD predefined names, changes
related to the DMAR and PCCT tables and ARM support among other
things) and cleanups related to using ACPICA's header files. A
major part of it is related to acpidump and the core code used by
that utility. Changes from Bob Moore, David E Box, Lv Zheng,
Sascha Wildner, Tomasz Nowicki, Hanjun Guo.
- Radix trees for memory bitmaps used by the hibernation core from
Joerg Roedel.
- Support for waking up the system from suspend-to-idle (also known
as the "freeze" sleep state) using ACPI-based PCI wakeup signaling
(Rafael J Wysocki).
- Fixes for issues related to ACPI button events (Rafael J Wysocki).
- New device ID for an ACPI-enumerated device included into the
Wildcat Point PCH from Jie Yang.
- ACPI video updates related to backlight handling from Hans de Goede
and Linus Torvalds.
- Preliminary changes needed to support ACPI on ARM from Hanjun Guo
and Graeme Gregory.
- ACPI PNP core cleanups from Arjun Sreedharan and Zhang Rui.
- Cleanups related to ACPI_COMPANION() and ACPI_HANDLE() macros
(Rafael J Wysocki).
- ACPI-based device hotplug cleanups from Wei Yongjun and Rafael J

All other add functions for lists have the new item as first argument and the position where it is added as second argument. This was changed for no good reason in this function and makes using it unnecessary confusing.

printk: allow increasing the ring buffer depending on the number of CPUs
The default size of the ring buffer is too small for machines with a large amount of CPUs under heavy load. What ends up happening when debugging is the ring buffer overlaps and chews up old messages making debugging impossible unless the size is passed as a kernel parameter. An idle system upon boot up will on average spew out only about one or two extra lines but where this really matters is on heavy load and that will vary widely depending on the system and environment. There are mechanisms to help increase the kernel ring buffer for tracing through debugfs, and those interfaces even allow growing the kernel ring buffer per CPU. We also have a static value which can be passed upon boot. Relying on debugfs however is not ideal for production, and relying on the value passed upon bootup is can only used *after* an issue has creeped up. Instead of being reactive this adds a proactive measure which lets you scale the amount of contributions you'd expect to the kernel ring buffer under load by each CPU in the worst case scenario. We use num_possible_cpus() to avoid complexities which could be introduced by dynamically changing the ring buffer size at run time, num_possible_cpus() lets us use the upper limit on possible number of CPUs therefore avoiding having to deal with hotplugging CPUs on and off. This introduces the kernel configuration option LOG_CPU_MAX_BUF_SHIFT which is used to specify the maximum amount of contributions to the kernel ring buffer in the worst case before the kernel ring buffer flips over, the size is specified as a power of 2. The total amount of contributions made by each CPU must be greater than half of the default kernel ring buffer size (1 << LOG_BUF_SHIFT bytes) in order to trigger an increase upon bootup. The kernel ring buffer is increased to the next power of two that would fit the required minimum kernel ring buffer size plus the additional CPU contribution. For example if LOG_BUF_SHIFT is 18 (256 KB) you'd require at least 128 KB contributions by other CPUs in order to trigger an increase of the kernel ring buffer. With a LOG_CPU_BUF_SHIFT of 12 (4 KB) you'd require at least anything over > 64 possible CPUs to trigger an increase. If you had 128 possible CPUs the amount of minimum required kernel ring buffer bumps to: ((1 << 18) + ((128 - 1) * (1 << 12))) / 1024 = 764 KB Since we require the ring buffer to be a power of two the new required size would be 1024 KB. This CPU contributions are ignored when the "log_buf_len" kernel parameter is used as it forces the exact size of the ring buffer to an expected power of two value.

- A fast NMI safe accessor to clock monotonic for tracing. This is a
long standing request to support correlated user/kernel space
traces. With proper NTP frequency correction it's also suitable
for correlation of traces accross separate machines.
- Checkpoint/restart support for timerfd.
- A few NOHZ[_FULL] improvements in the [hr]timer code.
- Code move from kernel to kernel/time of all time* related code.
- New clocksource/event drivers from the ARM universe. I'm really
impressed that despite an architected timer in the newer chips SoC
manufacturers insist on inventing new and differently broken SoC
specific timers.
[ Ed. "Impressed"? I don't think that word means what you think it means ]
- Another round of code move from arch to drivers. Looks like most
of the legacy mess in ARM regarding timers is sorted out except for
a few obnoxious strongholds.
- The usual updates and fixlets all over the place"

regulator: Updates for v3.17
A couple of nice new features this month, the ability to map regulators
in order to allow voltage control by external coprocessors is something
people have been asking for for a long time.
- Improved support for switch only "regulators", allowing current state
to be read from the parent regulator but no setting.
- Support for obtaining the register access method used to set
voltages, for use in systems which can offload control of this to a
coprocessor (typically for DVFS).
- Support for Active-Semi AC8846, Dialog DA9211 and Texas Instruments
TPS65917.

Last, we added support for reading the codec and MWS setting for controllers that support these features.' Additionally there are fixes to LE scanning, an update to conform to the 4.1 core specification as well as fixes for tracking the page scan state. All of these fixes are important for 3.17." And, "We've got: - 6lowpan fixes/cleanups - A couple crash fixes, one for the Marvell HCI driver and another in LE SMP. - Fix for an incorrect connected state check - Fix for the bondable requirement during pairing (an issue which had crept in because of using "pairable" when in fact the actual meaning was "bondable" (these have different meanings in Bluetooth)" Along with those are some late-breaking hardware support patches in brcmfmac and b43 as well as a stray ath9k patch. ==================== Signed-off-by: David S.

few days. MIPS and s390 have little going on this release; just bugfixes, some small, some larger. The highlights for x86 are nested VMX improvements (Jan Kiszka), optimizations for old processor (up to Nehalem, by me and Bandan Das), and a lot of x86 emulator bugfixes (Nadav Amit). Stephen Rothwell reported a trivial conflict with the tracing branch. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABAgAGBQJT300XAAoJEBvWZb6bTYby3V8QAJz+XyajnhJ8wH55Vxczz22L i2gtUGmBLhEXsBcaVKO4BBfek88lLzg0SGLjfW5wCMQmKtxVlrwTCXNkBoPGjapd NwHtWkMKym44PDhRovn7zkSumkxC43uFIBR/ebrhP6Bvhh9s+MnkQUxfw9ILB+YV EeKyEG8sSgxFCciuHbp3mIXpDcO6r/ldy6I7009OdyhLoMY+Kvmk7kRe9wtAivdg CGJi60QvGOn2RGRPOCEtF6UWr8Ae8fe1t84o0hkXPv/j3jtabzAatXKJa4dYNbIs 7Mp4NQpxaGV6rq3WCYVeZRxGs+UReGDAS3Il4Z8C9eTOTooSfxdVr8acpM8PY6I8 UmLT6ECLGycc4ELXrETtR+QLmiXACyJqyVxz4aiLV3kWSWfamKD3hBeQK9NizNcE VoPDl+PyISvR1tW4KstBuzfUWAEXi+gO78cqqFr/VW6cl7HKpA1DFQaPfGkYKDae 2CPwcLwI5/M6RtSgkyXTkEqNZLc2BjldqSeM1lmWjhZVW56X2iqePUL46Vab3Yvt U+sELtwEE560NLN3hbaHUsLR1tcUix5w8vTzcXPxgoHQBszHCcAZTWd1XHulr64F rp/cangqtkPKcu5j1mNhQs38oLjHI1MUsbQrqFoD4tmHjQ75iXHRFzYGoIVKXyHG AnGbQzJzBcdAANhm3LW0 =UXxV -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm Pull KVM changes from Paolo Bonzini: "These are the x86, MIPS and s390 changes; PPC and ARM will come in a few days.

This pull request has a lot of work done. The main thing is the changes
to the ftrace function callback infrastructure. It's introducing a way to allow different functions to call directly different trampolines instead of all calling the same "mcount" one. The only user of this for now is the function graph tracer, which always had a different trampoline, but the function tracer trampoline was called and did basically nothing, and then the function graph tracer trampoline was called. The difference now, is that the function graph tracer trampoline can be called directly if a function is only being traced by the function graph trampoline. If function tracing is also happening on the same function, the old way is still done. The accounting for this takes up more memory when function graph tracing is activated, as it needs to keep track of which functions it uses. I have a new way that wont take as much memory, but it's not ready yet for this merge window, and will have to wait for the next one. Another big change was the removal of the ftrace_start/stop() calls that were used by the suspend/resume code that stopped function tracing when entering into suspend and resume paths. The stop of ftrace was done because there was some function that would crash the system if one called smp_processor_id()! The stop/start was a big hammer to solve the issue at the time, which was when ftrace was first introduced into Linux. Now ftrace has better infrastructure to debug such issues, and I found the problem function and labeled it with "notrace" and function tracing can now safely be activated all the way down into the guts of suspend and resume. Other changes include clean ups of uprobe code. Clean up of the trace_seq() code. And other various small fixes and clean ups to ftrace and tracing. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJT35zXAAoJEKQekfcNnQGuOz0H/38zqM0nLFhrgvz3EPk2UOjn xqpX8qyb2V7TJZL+IqeXU2a5cQZl5ba0D4WtBGpxbTae3CJYiuQ87iKUNFoH0om5 FDpn80igb368k8V3qRdRsziKVCCf0XBd/NkHJXc0ZkfXGyzB2Ga4bBxALxp2gj9y bnO+vKo6+tWYKG4hyQb4P3LRXUrK8/LWEsPr39cH2QH1Rdj69Lx9CgrCdUVJmwcb Bj8hEiLXL/RYCFNn79A3wNTUvW0rG/AOIf4SLqXtasSRZ0ToaU0ZyDnrNv+0Ol47 rX8tSk+LfXchL9hpIvjCf1vlAYq3pO02favteR/jip3lx/dTjEDE4RJ9qtJzZ4Q= =fwQY -----END PGP SIGNATURE----- Merge tag 'trace-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "This pull request has a lot of work done.
