fs/f2fs: Use the enum req_op and blk_opf_t types
Improve static type checking by using the enum req_op type for variables that represent a request operation and the new blk_opf_t type for variables that represent request flags.

io_uring: move io_uring_get_opcode out of TP_printk
The TP_printk macro's are not supposed to use custom code ([1]) or else
tools such as perf cannot use these events.
Convert the opcode string representation to use the __string wiring that
the event framework provides ([2]).

workqueue: Fix type of cpu in trace event
The trace event "workqueue_queue_work" use unsigned int type for req_cpu, cpu. This casue confusing cpu number like below log. $ cat /sys/kernel/debug/tracing/trace cat-317 [001] ...: workqueue_queue_work: ... req_cpu=8192 cpu=4294967295 So, change unsigned type to signed type in the trace event. After applying this patch, cpu number will be printed as -1 instead of 4294967295 as folllows. $ cat /sys/kernel/debug/tracing/trace cat-1338 [002] ...: workqueue_queue_work: ... req_cpu=8192 cpu=-1 Cc: Baik Song An <bsahn@etri.re.kr> Cc: Hong Yeon Kim <kimhy@etri.re.kr> Cc: Taeung Song <taeung@reallinux.co.kr> Cc: linuxgeek@linuxgeek.io Signed-off-by: Wonhyuk Yang <vvghjk1234@gmail.com> Signed-off-by: Tejun Heo <tj@kernel.org> |

Driver core changes for 5.19-rc1
Here is the set of driver core changes for 5.19-rc1. Note, I'm not really happy with this pull request as-is, see below for details, but overall this is all good for everything but a small set of systems, which we have a fix for already. Lots of tiny driver core changes and cleanups happened this cycle, but the two major things were: - firmware_loader reorganization and additions including the ability to have XZ compressed firmware images and the ability for userspace to initiate the firmware load when it needs to, instead of being always initiated by the kernel. FPGA devices specifically want this ability to have their firmware changed over the lifetime of the system boot, and this allows them to work without having to come up with yet-another-custom-uapi interface for loading firmware for them. - physical location support added to sysfs so that devices that know this information, can tell userspace where they are located in a common way. Some ACPI devices already support this today, and more bus types should support this in the future. Smaller changes included: - driver_override api cleanups and fixes - error path cleanups and fixes - get_abi script fixes - deferred probe timeout changes. It's that last change that I'm the most worried about. It has been reported to cause boot problems for a number of systems, and I have a tested patch series that resolves this issue. But I didn't get it merged into my tree before 5.18-final came out, so it has not gotten any linux-next testing. I'll send the fixup patches (there are 2) as a follow-on series to this pull request if you want to take them directly, _OR_ I can just revert the probe timeout changes and they can wait for the next -rc1 merge cycle. Given that the fixes are tested, and pretty simple, I'm leaning toward that choice. Sorry this all came at the end of the merge window, I should have resolved this all 2 weeks ago, that's my fault as it was in the middle of some travel for me. All have been tested in linux-next for weeks, with no reported issues other than the above-mentioned boot time outs.

f2fs-for-5.19
In this round, we've refactored the existing atomic write support implemented by in-memory operations to have storing data in disk temporarily, which can give us a benefit to accept more atomic writes. At the same time, we removed the existing volatile write support. We've also revisited the file pinning and GC flows and found some corner cases which contributeed abnormal system behaviours. As usual, there're several minor code refactoring for readability, sanity check, and clean ups. Enhancement - allow compression for mmap files in compress_mode=user - kill volatile write support - change the current atomic write way - give priority to select unpinned section for foreground GC - introduce data read/write showing path info - remove unnecessary f2fs_lock_op in f2fs_new_inode Bug fix - fix the file pinning flow during checkpoint=disable and GCs - fix foreground and background GCs to select the right victims and get free sections on time - fix GC flags on defragmenting pages - avoid an infinite loop to flush node pages - fix fallocate to use file_modified to update permissions consistently -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmKWfyEACgkQQBSofoJI UNJaAQ/9Hs3aGIyriGV8CMbarklRuQ24o3khQKdia5gHseFVsydMfba8tyvl7vYV fZnHKp9rnEV1emxWn7hHLaGOvPV8leajZqMLhqG384BIb0yoTnRipnK5t0JkoiJX 53XC5yfxQd01dwS+J4uOSu2jW0Gs6iBLD6H9ahOs86OE6jF1TeQ/fqjsrhm9I8Zr GsNON6zxafPn248sYyVBB3Y5GjPBPf+USif3ZEidAWimW/TIGbXLUT1hA0B79YoX DRAmN3tYS75yXauQvFPerMbOmP2gwCPcvdCI/PZ4U/ApsEPP7k1SbOZYAjjGUB30 Qn8cSMxzPZ1cHvzIC96vwJk8XPdcDhICfzROb7jJdeznD8cWTDv0E+Vd33HUf/mG pi5Lkpc4STvYD+KUaKpdnHVg6ARWw4HOnUtW43MF3OsfuyGEEPlROs6lBVYnk/Hz smlrgnnLMTOpH9y2JyuyExeHEJ3EAgWbJ8aRpq7Ua7FvKF45Yj1lIytWlvWXSnRf rp+A5QJhVtYvT+y2Rk2h5oTRj/9l3+pR0X7CTOfSivJuf6aH5XVgI0EmxT2iBTCp 4SDBjLC+nXXP3EK1HamLiz1mU23Qg1Qwvx3Wc4xgdwQf3s+jyYxki9tIjzdwJCCZ adjd3fc/GrD9UPDmJDXlD5QSoOJ94K/NOwYpu1L1/Q+dVwkl+IE= =ta8Y -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've refactored the existing atomic write support implemented by in-memory operations to have storing data in disk temporarily, which can give us a benefit to accept more atomic writes.

NFSD 5.19 Release Notes
We introduce "courteous server" in this release. Previously NFSD would purge open and lock state for an unresponsive client after one lease period (typically 90 seconds). Now, after one lease period, another client can open and lock those files and the unresponsive client's lease is purged; otherwise if the unrespon- sive client's open and lock state is uncontended, the server retains that open and lock state for up to 24 hours, allowing the client's workload to resume after a lengthy network partition. A longstanding issue with NFSv4 file creation is also addressed. Previously a file creation can fail internally, returning an error to the client, but leave the newly created file in place as an artifact. The file creation code path has been reorganized so that internal failures and race conditions are less likely to result in an unwanted file creation. A fault injector has been added to help exercise paths that are run during kernel metadata cache invalidation. These caches contain information maintained by user space about exported filesystems. Many of our test workloads do not trigger cache invalidation. There is one patch that is needed to support PREEMPT_RT and a fix for an ancient "sleep while spin-locked" splat that seems to have become easier to hit since v5.18-rc3. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmKPliAACgkQM2qzM29m f5dB3BAAorPa2L8xu5P1Ge1oTNogNSOVRkLPDzEkfEwK07ZM2qvz78eMZGkMziJ/ strorvBWl3SWBlVtTePgNpJUjgYQ75MRRwaX7Qh2WuHeRKm1JlZm0/NId3+zKgbh N40QI20jdswWcNDuhidxVFFWurd09GlcM4z1cu8gZLbfthkiUOjZoPiLkXeNcvhk 7wC9GiueWxHefYQQDAKh1nQS/L0GG1EkzJdJo7WUVAldZ9qVY9LpmJVMRqrBBbta XrFYfpeY1zFFDY4Qolyz5PUJSeQuDj9PctlhoZ6B1hp56PD/6yaqVhYXiPxtlALj tITtktfiekULZkgfvfvyzssCv+wkbYiaEBZcSSCauR7dkGOmBmajO+cf7vpsERgE fbCU8DWGk78SMeehdCrO+26cV37VP+8c2t2Txq/rG5Eq4ZoCi++Hj5poRboFLqb+ oom+0Ee0LfcAKXkxH5gWTPTblHo49GzGitPZtRzTgZ9uFnVwvEaJ4+t0ij0J8JpL HuVtWrg5/REhqpEvOSwF0sRmkYWLTu7KdueGn/iZ8xUi7GHEue01NsVkClohKJcR WOjWrbNCNF/LJaG88MX0z5u7IO7s9bOHphd7PJ92vR+4YsehW3uRhk+rNi2ZBqQz hzULfu8BiaicV9fdB/hDcMmKQD6U6due2AVVPtxTf5XY+CHQNRY= =phE1 -----END PGP SIGNATURE----- Merge tag 'nfsd-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "We introduce 'courteous server' in this release.

Yang Shi has improved the behaviour of khugepaged collapsing of readonly
file-backed transparent hugepages. Johannes Weiner has arranged for zswap memory use to be tracked and managed on a per-cgroup basis. Munchun Song adds a /proc knob ("hugetlb_optimize_vmemmap") for runtime enablement of the recent huge page vmemmap optimization feature. Baolin Wang contributes a series to fix some issues around hugetlb pagetable invalidation. Zhenwei Pi has fixed some interactions between hwpoisoned pages and virtualization. Tong Tiangen has enabled the use of the presently x86-only page_table_check debugging feature on arm64 and riscv. David Vernet has done some fixup work on the memcg selftests. Peter Xu has taught userfaultfd to handle write protection faults against shmem- and hugetlbfs-backed files. More DAMON development from SeongJae Park - adding online tuning of the feature and support for monitoring of fixed virtual address ranges. Also easier discovery of which monitoring operations are available. Nadav Amit has done some optimization of TLB flushing during mprotect(). Neil Brown continues to labor away at improving our swap-over-NFS support. David Hildenbrand has some fixes to anon page COWing versus get_user_pages(). Peng Liu fixed some errors in the core hugetlb code. Joao Martins has reduced the amount of memory consumed by device-dax's compound devmaps. Some cleanups of the arch-specific pagemap code from Anshuman Khandual. Muchun Song has found and fixed some errors in the TLB flushing of transparent hugepages. Roman Gushchin has done more work on the memcg selftests. And, of course, many smaller fixes and cleanups.

Hopefully it could bring more possibility to the communities. The story mainly started from a new project what we called "RAFS v6" [1] for Nydus image service almost a year ago, which enhances EROFS to be a new form of one bootstrap (which includes metadata representing the whole fs tree) + several data-deduplicated content addressable blobs (actually treated as multiple devices). Each blob can represent one container image layer but not quite exactly since all new data can be fully existed in the previous blobs so no need to introduce another new blob. It is actually not a new idea (at least on my side it's much like a simpilied casync [2] for now) and has many benefits over per-file blobs or some other exist ways since typically each RAFS v6 image only has dozens of device blobs instead of thousands of per-file blobs. It's easy to be signed with user keys as a golden image, transfered untouchedly with minimal overhead over the network, kept in some type of storage conveniently, and run with (optional) runtime verification but without involving too many irrelevant features crossing the system beyond EROFS itself. At least it's our final goal and we're keeping working on it. There was also a good summary of this approach from the casync author [3]. Regardless further optimizations, this work is almost done in the previous Linux release cycles. In this round, we'd like to introduce on-demand load for EROFS with the fscache/cachefiles infrastructure, considering the following advantages: - Introduce new file-based backend to EROFS. Although each image only contains dozens of blobs but in densely-deployed runC host for example, there could still be massive blobs on a machine, which is messy if each blob is treated as a device. In contrast, fscache and cachefiles are really great interfaces for us to make them work. - Introduce on-demand load to fscache and EROFS. Previously, fscache is mainly used to caching network-likewise filesystems, now it can support on-demand downloading for local fses too with the exact localfs on-disk format. It has many advantages which we're been described in the latest patchset cover letter [4]. In addition to that, most importantly, the cached data is still stored in the original local fs on-disk format so that it's still the one signed with private keys but only could be partially available. Users can fully trust it during running. Later, users can also back up cachefiles easily to another machine. - More reliable on-demand approach in principle. After data is all available locally, user daemon can be no longer online in some use cases, which helps daemon crash recovery (filesystems can still in service) and hot-upgrade (user daemon can be upgraded more frequently due to new features or protocols introduced.) - Other format can also be converted to EROFS filesystem format over the internet on the fly with the new on-demand load feature and mounted. That is entirely possible with on-demand load feature as long as such archive format metadata can be fetched in advance like stargz. In addition, although currently our target user is Nydus image service [5], but laterly, it can be used for other use cases like on-demand system booting, etc. As for the fscache on-demand load feature itself, strictly it can be used for other local fses too. Laterly we could promote most code to the iomap infrastructure and also enhance it in the read-write way if other local fses are interested. Thanks David Howells for taking so much time and patience on this these months, many thanks with great respect here again! Thanks Jeffle for working on this feature and Xin Yin from Bytedance for asynchronous I/O implementation as well as Zichen Tian, Jia Zhu, and Yan Song for testing, much appeciated. We're also exploring more possibly over fscache cache management over FSDAX for secure containers and working on more improvements and useful features for fscache, cachefiles, and on-demand load. In addition to "erofs over fscache", NFS export and idmapped mount are also completed in this cycle for container use cases as well.

Updates for timers and timekeeping core code:
- Expose CLOCK_TAI to instrumentation to aid with TSN debugging. - Ensure that the clockevent is stopped when there is no timer armed to avoid pointless wakeups. - Make the sched clock frequency handling and rounding consistent. - Provide a better debugobject hint for delayed works.

rxrpc: Fix decision on when to generate an IDLE ACK
Fix the decision on when to generate an IDLE ACK by keeping a count of the
number of packets we've received, but not yet soft-ACK'd, and the number of
packets we've processed, but not yet hard-ACK'd, rather than trying to keep
track of which DATA sequence numbers correspond to those points.
We then generate an ACK when either counter exceeds 2. The counters are
both cleared when we transcribe the information into any sort of ACK packet

cachefiles: notify the user daemon when looking up cookie
Fscache/CacheFiles used to serve as a local cache for a remote networking fs. A new on-demand read mode will be introduced for CacheFiles, which can boost the scenario where on-demand read semantics are needed, e.g. container image distribution. The essential difference between these two modes is seen when a cache miss occurs: In the original mode, the netfs will fetch the data from the remote server and then write it to the cache file; in on-demand read mode, fetching the data and writing it into the cache is delegated to a user daemon. As the first step, notify the user daemon when looking up cookie. In this case, an anonymous fd is sent to the user daemon, through which the user daemon can write the fetched data to the cache file. Since the user daemon may move the anonymous fd around, e.g. through dup(), an object ID uniquely identifying the cache file is also attached. Also add one advisory flag (FSCACHE_ADV_WANT_CACHE_SIZE) suggesting that the cache file size shall be retrieved at runtime. This helps the scenario where one cache file contains multiple netfs files, e.g. for the purpose of deduplication. In this case, netfs itself has no idea the size of the cache file, whilst the user daemon should give the hint on it.

f2fs: change the current atomic write way
Current atomic write has three major issues like below. - keeps the updates in non-reclaimable memory space and they are even hard to be migrated, which is not good for contiguous memory allocation. - disk spaces used for atomic files cannot be garbage collected, so this makes it difficult for the filesystem to be defragmented. - If atomic write operations hit the threshold of either memory usage or garbage collection failure count, All the atomic write operations will fail immediately. To resolve the issues, I will keep a COW inode internally for all the updates to be flushed from memory, when we need to flush them out in a situation like high memory pressure. These COW inodes will be tagged as orphan inodes to be reclaimed in case of sudden power-cut or system failure during atomic writes.

arch_topology: Trace the update thermal pressure
Add trace event to capture the moment of the call for updating the thermal pressure value. It's helpful to investigate how often those events occur in a system dealing with throttling. This trace event is needed since the old 'cdev_update' might not be used by some drivers. The old 'cdev_update' trace event only provides a cooling state value: [0, n]. That state value then needs additional tools to translate it: state -> freq -> capacity -> thermal pressure. This new trace event just stores proper thermal pressure value in the trace buffer, no need for additional logic. This is helpful for cooperation when someone can simply sends to the list the trace buffer output from the platform (no need from additional information from other subsystems). There are also platforms which due to some design reasons don't use cooling devices and thus don't trigger old 'cdev_update' trace event. They are also important and measuring latency for the thermal signal raising/decaying characteristics is in scope. This new trace event would cover them as well. We already have a trace point 'pelt_thermal_tp' which after a change to trace event can be paired with this new 'thermal_pressure_update' and derive more insight what is going on in the system under thermal pressure (and why).

io_uring: use the text representation of ops in trace
It is annoying to translate opcodes to textwhen tracing io_uring. Use the io_uring_get_opcode function instead to use the text representation. A downside here might have been that if the opcode is invalid it will not be obvious, however the opcode is already overridden in these cases to 0 (NOP) in io_init_req(). Therefore this is a non issue.
