When boxes are run near (or to) OOM, we have a problem with the discard
page allocation in sd. If we fail allocating the special page, we return
busy, and it'll get retried. But since ordering is honored for dispatch
requests, we can keep retrying this same IO and failing. Behind that IO
could be requests that want to free memory, but they never get the
chance. This means you get repeated spews of traces like this:

Several conflicts, seemingly all over the place.
I used Stephen Rothwell's sample resolutions for many of these, if not
just to double check my own work, so definitely the credit largely
goes to him.
The NFP conflict consisted of a bug fix (moving operations
past the rhashtable operation) while chaning the initial
argument in the function call in the moved code.
The net/dsa/master.c conflict had to do with a bug fix intermixing of
making dsa_master_set_mtu() static with the fixing of the tagging
attribute location.
cls_flower had a conflict because the dup reject fix from Or
overlapped with the addition of port range classifiction.
__set_phy_supported()'s conflict was relatively easy to resolve
because Andrew fixed it in both trees, so it was just a matter
of taking the net-next copy. Or at least I think it was :-)
Joe Stringer's fix to the handling of netns id 0 in bpf_sk_lookup()
intermixed with changes on how the sdif and caller_net are calculated
in these code paths in net-next.
The remaining BPF conflicts were largely about the addition of the
__bpf_md_ptr stuff in 'net' overlapping with adjustments and additions
to the relevant data structure where the MD pointer macros are used.

Pull SCSI fixes from James Bottomley:
"Four obvious bug fixes. The vmw_pscsi is so old that it's amazing
no-one noticed before now"
* tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi:
scsi: storvsc: Fix a race in sub-channel creation that can cause panic
scsi: vmw_pscsi: Rearrange code to avoid multiple calls to free_irq during unload
scsi: libiscsi: Fix NULL pointer dereference in iscsi_eh_session_reset
scsi: lpfc: fix block guard enablement on SLI3 adapters
We can concurrently try to open the same sub-channel from 2 paths:
path #1: vmbus_onoffer() -> vmbus_process_offer() -> handle_sc_creation().
path #2: storvsc_probe() -> storvsc_connect_to_vsp() ->
-> storvsc_channel_init() -> handle_multichannel_storage() ->
-> vmbus_are_subchannels_present() -> handle_sc_creation().
They conflict with each other, but it was not an issue before the recent
commit ae6935ed7d ("vmbus: split ring buffer allocation from open"),
because at the beginning of vmbus_open() we checked newchannel->state so
only one path could succeed, and the other would return with -EINVAL.
After ae6935ed7d, the failing path frees the channel's ringbuffer by
vmbus_free_ring(), and this causes a panic later.
Commit ae6935ed7d itself is good, and it just reveals the longstanding
race. We can resolve the issue by removing path #2, i.e. removing the
second vmbus_are_subchannels_present() in handle_multichannel_storage().
BTW, the comment "Check to see if sub-channels have already been created"
in handle_multichannel_storage() is incorrect: when we unload the driver,
we first close the sub-channel(s) and then close the primary channel, next
the host sends rescind-offer message(s) so primary->sc_list will become
empty. This means the first vmbus_are_subchannels_present() in
handle_multichannel_storage() is never useful.

c2856ae2f3 ("blk-mq: quiesce queue before freeing queue") has
already fixed this race, however the implied synchronize_rcu()
in blk_mq_quiesce_queue() can slow down LUN probe a lot, so caused
performance regression.
Then 1311326cf4 ("blk-mq: avoid to synchronize rcu inside blk_cleanup_queue()")
tried to quiesce queue for avoiding unnecessary synchronize_rcu()
only when queue initialization is done, because it is usual to see
lots of inexistent LUNs which need to be probed.
However, turns out it isn't safe to quiesce queue only when queue
initialization is done. Because when one SCSI command is completed,
the user of sending command can be waken up immediately, then the
scsi device may be removed, meantime the run queue in scsi_end_request()
is still in-progress, so kernel panic can be caused.
In Red Hat QE lab, there are several reports about this kind of kernel
panic triggered during kernel booting.
This patch tries to address the issue by grabing one queue usage
counter during freeing one request and the following run queue.

Reading throught the new driver, I noticed that this cannot work on
big-endian CPUs, and the old DAC960 had exactly the same behavior.
To document this for the future, add a Kconfig dependency that prevents it
from being included in big-endian kernels. Since the hardware is really
old and we never had a working driver on it for big-endian platforms,
it's unlikely to make a difference to users.

Drivers exposing zoned block devices have to initialize and maintain
correctness (i.e. revalidate) of the device zone bitmaps attached to
the device request queue (seq_zones_bitmap and seq_zones_wlock).
To simplify coding this, introduce a generic helper function
blk_revalidate_disk_zones() suitable for most (and likely all) cases.
This new function always update the seq_zones_bitmap and seq_zones_wlock
bitmaps as well as the queue nr_zones field when called for a disk
using a request based queue. For a disk using a BIO based queue, only
the number of zones is updated since these queues do not have
schedulers and so do not need the zone bitmaps.
With this change, the zone bitmap initialization code in sd_zbc.c can be
replaced with a call to this function in sd_zbc_read_zones(), which is
called from the disk revalidate block operation method.
A call to blk_revalidate_disk_zones() is also added to the null_blk
driver for devices created with the zoned mode enabled.
Finally, to ensure that zoned devices created with dm-linear or
dm-flakey expose the correct number of zones through sysfs, a call to
blk_revalidate_disk_zones() is added to dm_table_set_restrictions().
The zone bitmaps allocated and initialized with
blk_revalidate_disk_zones() are freed automatically from
__blk_release_queue() using the block internal function
blk_queue_free_zone_bitmaps().

Dispatching a report zones command through the request queue is a major
pain due to the command reply payload rewriting necessary. Given that
blkdev_report_zones() is executing everything synchronously, implement
report zones as a block device file operation instead, allowing major
simplification of the code in many places.
sd, null-blk, dm-linear and dm-flakey being the only block device
drivers supporting exposing zoned block devices, these drivers are
modified to provide the device side implementation of the
report_zones() block device file operation.
For device mappers, a new report_zones() target type operation is
defined so that the upper block layer calls blkdev_report_zones() can
be propagated down to the underlying devices of the dm targets.
Implementation for this new operation is added to the dm-linear and
dm-flakey targets.

The unsigned 32 bits overflow check for the zone size value is already
done within sd_zbc_check_zones() with the test:
} else if (logical_to_sectors(sdkp->device, zone_blocks) > UINT_MAX) {
so there is no need to check again for an out of range value in
sd_zbc_read_zones(). Simplify the code and fix sd_zbc_check_zones()
error return to -EFBIG instead of -ENODEV if the zone size is too large.
Change the return type of sd_zbc_check_zones() to an int for the error
code and return the zone size (zone_blocks) through a u32 pointer to
avoid overflowing the signed 32 return value.

Handling checks of ZBC device capacity using the max_lba field of the
REPORT ZONES command reply for disks with rc_basis == 0 can be done
using the same report zones command reply used to check the "same"
field.
Avoid executing a report zones command solely to check the disk capacity
by merging sd_zbc_check_capacity() into sd_zbc_check_zone_size() and
renaming that function to sd_zbc_check_zones(). This removes a costly
execution of a full report zones command and so reduces device scan
duration at boot time as well as the duration of disk revalidate calls.
Furthermore, setting the partial report bit in the REPORT ZONES command
cdb can significantly reduce this command execution time as the device
does not have to count and report the total number of zones that could
be reported assuming a large enough reply buffer. A non-partial zone
report is necessary only for the first execution of report zones used to
check the same field value (to ensure that this value applies to all
zones of the disk). All other calls to sd_zbc_report_zones() can use a
partial report to reduce execution time.
Using a 14 TB ZBC disk, these simple changes reduce device scan time at
boot from about 3.5s down to about 900ms. Disk revalidate times are also
reduced from about 450ms down to 230ms.

Move the urswrz check out of sd_zbc_read_zones() and into
sd_zbc_read_zoned_characteristics() where that value is obtained (read
from the disk zoned characteristics VPD page). Since this function now
does more than simply reading the VPD page, rename it to
sd_zbc_check_zoned_characteristics().
Also fix the error message displayed when reading that VPD page fails.

Pull SCSI updates from James Bottomley:
"This is mostly updates of the usual drivers: UFS, esp_scsi, NCR5380,
qla2xxx, lpfc, libsas, hisi_sas.
In addition there's a set of mostly small updates to the target
subsystem a set of conversions to the generic DMA API, which do have
some potential for issues in the older drivers but we'll handle those
as case by case fixes.
A new myrs driver for the DAC960/mylex raid controllers to replace the
block based DAC960 which is also being removed by Jens in this merge
window.
Plus the usual slew of trivial changes"
[ "myrs" stands for "MYlex Raid Scsi". Obviously. Silly of me to even
wonder. There's also a "myrb" driver, where the 'b' stands for
'block'. Truly, somebody has got mad naming skillz. - Linus ]
