For the boot-on/always-on regulators the set_machine_constrainst() is
called before resolving rdev->supply. Thus the code would try to enable
rdev before enabling supplying regulator. Enforce resolving supply
regulator before enabling rdev.

While include/linux/bitops.h brings in the BIT() macro, it was moved to
include/linux/bits.h in commit 8bd9cb51daac ("locking/atomics, asm-generic:
Move some macros from <linux/bitops.h> to a new <linux/bits.h> file").
Since that commit BIT() has moved again into include/vdso/bits.h via
commit 3945ff37d2f4 ("linux/bits.h: Extract common header for vDSO").
I think the move to the vDSO header can be considered an implementation
detail, so for now update the checkpatch documentation to recommend use
of include/linux/bits.h.

It should use post_handler instead of pre_handler in handler_post().
As Joe Perches suggested, it would be better to use pr_fmt and remove
all the embedded pre/post/fault strings. This would change the style of

./scripts/get_abi.pl is warning about duplicated symbol
definition:
Warning: /sys/class/backlight/<backlight>/l1_daylight_max is defined 2 times: ./Documentation/ABI/testing/sysfs-class-backlight-driver-adp8870:4 ./Documentation/ABI/testing/sysfs-class-backlight-adp8860:12
What happens is that 3 drivers use the same pattern to report
max and dim setting for different ambient light zones.
It should be noticed that the adp8870 doc was missing an
entry for l1_daylight_dim, which was fixed on this patch.
While the ambient light zone is device-specific, the sysfs
definition is actually common. So, unify them at:
Documentation/ABI/testing/sysfs-class-backlight
and use as the contact point, the e-mail reported by
get_maintainers.pl for the subsystem.

If VCPU is suspended (VM suspend) in wq_watchdog_timer_fn() then
once this VCPU resumes it will see the new jiffies value, while it
may take a while before IRQ detects PVCLOCK_GUEST_STOPPED on this
VCPU and updates all the watchdogs via pvclock_touch_watchdogs().
There is a small chance of misreported WQ stalls in the meantime,
because new jiffies is time_after() old 'ts + thresh'.
wq_watchdog_timer_fn()
{
for_each_pool(pool, pi) {
if (time_after(jiffies, ts + thresh)) {
pr_emerg("BUG: workqueue lockup - pool");
}
}
}
Save jiffies at the beginning of this function and use that value
for stall detection. If VM gets suspended then we continue using
"old" jiffies value and old WQ touch timestamps. If IRQ at some
point restarts the stall detection cycle (pvclock_touch_watchdogs())
then old jiffies will always be before new 'ts + thresh'.

potential fixes that were made by those individuals. I would like to
thank the over 80 different developers who helped with the review and

This patch effectively reverts the commit a3e72739b7a7 ("cgroup: fix
too early usage of static_branch_disable()"). The commit 6041186a3258
("init: initialize jump labels before command line option parsing") has
moved the jump_label_init() before parse_args() which has made the
commit a3e72739b7a7 unnecessary. On the other hand there are
consequences of disabling the controllers later as there are subsystems
doing the controller checks for different decisions. One such incident
is reported [1] regarding the memory controller and its impact on memory
reclaim code.

Pull quota fixes from Jan Kara:
"The most important part in the pull is disablement of the new syscall
quotactl_path() which was added in rc1.
The reason is some people at LWN discussion pointed out dirfd would be
useful for this path based syscall and Christian Brauner agreed.
Without dirfd it may be indeed problematic for containers. So let's
just disable the syscall for now when it doesn't have users yet so
that we have more time to mull over how to best specify the filesystem
we want to work on"

If a disconnection occurs while we're trying to reply to a server
callback, then we may end up calling xs_tcp_send_request() with a NULL
value for transport->inet, which trips up the call to
tcp_sock_set_cork().

Commit de144ff4234f changes _pnfs_return_layout() to call
pnfs_mark_matching_lsegs_return() passing NULL as the struct
pnfs_layout_range argument. Unfortunately,
pnfs_mark_matching_lsegs_return() doesn't check if we have a value here
before dereferencing it, causing an oops.
I'm able to hit this crash consistently when running connectathon basic
tests on NFS v4.1/v4.2 against Ontap.

If sunrpc.tcp_max_slot_table_entries is small and there are tasks
on the backlog queue, then when a request completes it is freed and the
first task on the queue is woken. The expectation is that it will wake
and claim that request. However if it was a sync task and the waiting
process was killed at just that moment, it will wake and NOT claim the
request.
As long as TASK_CONGESTED remains set, requests can only be claimed by
tasks woken from the backlog, and they are woken only as requests are
freed, so when a task doesn't claim a request, no other task can ever
get that request until TASK_CONGESTED is cleared. Each time this
happens the number of available requests is decreased by one.
With a sufficiently high workload and sufficiently low setting of
max_slot (16 in the case where this was seen), TASK_CONGESTED can remain
set for an extended period, and the above scenario (of a process being
killed just as its task was woken) can repeat until no requests can be
allocated. Then traffic stops.
This patch addresses the problem by introducing a positive handover of a
request from a completing task to a backlog task - the request is never
freed when there is a backlog.
When a task is woken it might not already have a request attached in
which case it is *not* freed (as with current code) but is initialised
(if needed) and used. If it isn't used it will eventually be freed by
rpc_exit_task(). xprt_release() is enhanced to be able to correctly
release an uninitialised request.
