ata: libata-scsi: rework ata_dump_status to avoid using pr_cont()
pr_cont() has the problem that individual calls will be disrupted
under high load, causing each call to end up on a single line and
thereby mangling the output.
So rework ata_dump_status() to have just one call to ata_port_warn()
and avoid this problem.

Notice how the events are listed twice.
The named commit changed how we remove duplicate events, in that events
for different PMUs are not treated as duplicates. I suppose this is to
handle how "Each hybrid pmu event has been assigned with a pmu name".
Fix PMU alias listing by restoring behaviour to remove duplicates for

mm: vmscan: reduce throttling due to a failure to make progress -fix
Hugh Dickins reported the following
My tmpfs swapping load (tweaked to use huge pages more heavily
than in real life) is far from being a realistic load: but it was
notably slowed down by your throttling mods in 5.16-rc, and this
patch makes it well again - thanks.
But: it very quickly hit NULL pointer until I changed that last
line to
if (first_pgdat)
consider_reclaim_throttle(first_pgdat, sc);
The likely issue is that huge pages are a major component of the test
workload. When this is the case, first_pgdat may never get set if
compaction is ready to continue due to this check
if (IS_ENABLED(CONFIG_COMPACTION) &&
sc->order > PAGE_ALLOC_COSTLY_ORDER &&
compaction_ready(zone, sc)) {
sc->compaction_ready = true;
continue;
}
If this was true for every zone in the zonelist, first_pgdat would never
get set resulting in a NULL pointer exception.

mm: vmscan: Reduce throttling due to a failure to make progress
Mike Galbraith, Alexey Avramov and Darrick Wong all reported similar
problems due to reclaim throttling for excessive lengths of time. In
Alexey's case, a memory hog that should go OOM quickly stalls for
several minutes before stalling. In Mike and Darrick's cases, a small
memcg environment stalled excessively even though the system had enough
memory overall.
Commit
69392a403f49 ("mm/vmscan: throttle reclaim when no progress is
being made") introduced the problem although commit
a19594ca4a8b
("mm/vmscan: increase the timeout if page reclaim is not making
progress") made it worse. Systems at or near an OOM state that cannot
be recovered must reach OOM quickly and memcg should kill tasks if a
memcg is near OOM.
To address this, only stall for the first zone in the zonelist, reduce
the timeout to 1 tick for VMSCAN_THROTTLE_NOPROGRESS and only stall if
the scan control nr_reclaimed is 0, kswapd is still active and there
were excessive pages pending for writeback. If kswapd has stopped
reclaiming due to excessive failures, do not stall at all so that OOM
triggers relatively quickly. Similarly, if an LRU is simply congested,
only lightly throttle similar to NOPROGRESS.
Alexey's original case was the most straight forward
for i in {1..3}; do tail /dev/zero; done
On vanilla 5.16-rc1, this test stalled heavily, after the patch the test
completes in a few seconds similar to 5.15.
Alexey's second test case added watching a youtube video while tail runs
10 times. On 5.15, playback only jitters slightly, 5.16-rc1 stalls a
lot with lots of frames missing and numerous audio glitches. With this
patch applies, the video plays similarly to 5.15.

mm/damon/dbgfs: fix 'struct pid' leaks in 'dbgfs_target_ids_write()'
DAMON debugfs interface increases the reference counts of 'struct pid's
for targets from the 'target_ids' file write callback
('dbgfs_target_ids_write()'), but decreases the counts only in DAMON
monitoring termination callback ('dbgfs_before_terminate()').
Therefore, when 'target_ids' file is repeatedly written without DAMON
monitoring start/termination, the reference count is not decreased and
therefore memory for the 'struct pid' cannot be freed. This commit
fixes this issue by decreasing the reference counts when 'target_ids' is
written.

userfaultfd/selftests: fix hugetlb area allocations
Currently, userfaultfd selftest for hugetlb as run from run_vmtests.sh
or any environment where there are 'just enough' hugetlb pages will
always fail with:
testing events (fork, remap, remove):
ERROR: UFFDIO_COPY error: -12 (errno=12, line=616)
The ENOMEM error code implies there are not enough hugetlb pages.
However, there are free hugetlb pages but they are all reserved. There
is a basic problem with the way the test allocates hugetlb pages which
has existed since the test was originally written.
Due to the way 'cleanup' was done between different phases of the test,
this issue was masked until recently. The issue was uncovered by commit
8ba6e8640844 ("userfaultfd/selftests: reinitialize test context in each
test").
For the hugetlb test, src and dst areas are allocated as PRIVATE
mappings of a hugetlb file. This means that at mmap time, pages are
reserved for the src and dst areas. At the start of event testing (and
other tests) the src area is populated which results in allocation of
huge pages to fill the area and consumption of reserves associated with
the area. Then, a child is forked to fault in the dst area. Note that
the dst area was allocated in the parent and hence the parent owns the
reserves associated with the mapping. The child has normal access to
the dst area, but can not use the reserves created/owned by the parent.
Thus, if there are no other huge pages available allocation of a page
for the dst by the child will fail.
Fix by not creating reserves for the dst area. In this way the child
can use free (non-reserved) pages.
Also, MAP_PRIVATE of a file only makes sense if you are interested in
the contents of the file before making a COW copy. The test does not do
this. So, just use MAP_ANONYMOUS | MAP_HUGETLB to create an anonymous
hugetlb mapping. There is no need to create a hugetlb file in the
non-shared case.

Pull drm fixes from Dave Airlie:
"This is a bit bigger than I'd like, however it has two weeks of amdgpu
fixes in it, since they missed last week, which was very small.
The nouveau regression is probably the biggest fix in here, and it
needs to go into 5.15 as well, two i915 fixes, and then a scattering
of amdgpu fixes. The biggest fix in there is for a fencing NULL
pointer dereference, the rest are pretty minor.
For the misc team, I've pulled the two misc fixes manually since I'm
not sure what is happening at this time of year!
The amdgpu maintainers have the outstanding runpm regression to fix
still, they are just working through the last bits of it now.
Summary:
nouveau:
- fencing regression fix
i915:
- Fix possible uninitialized variable
- Fix composite fence seqno icrement on each fence creation
amdgpu:
- Fencing fix
- XGMI fix
- VCN regression fix
- IP discovery regression fixes
- Fix runpm documentation
- Suspend/resume fixes
- Yellow Carp display fixes
- MCLK power management fix
- dma-buf fix"

This merges two fixes that haven't been sent to me yet, but I wanted to get in.
One amdgpu fix, but one nouveau regression fixer.

fs/mount_setattr: always cleanup mount_kattr
Make sure that finish_mount_kattr() is called after mount_kattr was
succesfully built in both the success and failure case to prevent
leaking any references we took when we built it. We returned early if
path lookup failed thereby risking to leak an additional reference we
took when building mount_kattr when an idmapped mount was requested.

"Including fixes from.. Santa?
No regressions on our radar at this point. The igc problem fixed here
was the last one I was tracking but it was broken in previous
releases, anyway. Mostly driver fixes and a couple of largish SMC
fixes.
Current release - regressions:
- xsk: initialise xskb free_list_node, fixup for a -rc7 fix
Current release - new code bugs:
- mlx5: handful of minor fixes:
- use first online CPU instead of hard coded CPU
- fix some error handling paths in 'mlx5e_tc_add_fdb_flow()'
- fix skb memory leak when TC classifier action offloads are disabled
- fix memory leak with rules with internal OvS port
Previous releases - regressions:
- igc: do not enable crosstimestamping for i225-V models
Previous releases - always broken:
- udp: use datalen to cap ipv6 udp max gso segments
- fix use-after-free in tw_timer_handler due to early free of stats
- smc: fix kernel panic caused by race of smc_sock
- smc: don't send CDC/LLC message if link not ready, avoid timeouts
- sctp: use call_rcu to free endpoint, avoid UAF in sock diag
- bridge: mcast: add and enforce query interval minimum
- usb: pegasus: do not drop long Ethernet frames
- mlx5e: fix ICOSQ recovery flow for XSK
- nfc: uapi: use kernel size_t to fix user-space builds"
