Preparatory patch to add ioctl that allows to forget a device (ie.
reverse of scan).
Refactors btrfs_free_stale_devices() to obtain return status. As this
function can fail if it can't find the given path (returns -ENOENT) or
trying to delete a mounted device (returns -EBUSY).

In order to avoid duplicating init code for em there is an additional

case when it will be used is if the extent we are adding overlaps with
an existing extent. Make that case more obvious by:
1. Adding a comment hinting at what's going on
2. Assigning EXTENT_MAP_HOLE and directly going to insert.

This function is a simple wrapper over btrfs_get_extent that returns
either:
a) A real extent in the passed range or
b) Adjusted extent based on whether delalloc bytes are found backing up
a hole.
To support these semantics it doesn't need the page/pg_offset/create
arguments which are passed to btrfs_get_extent in case an extent is to
be created. So simplify the function by removing the unused arguments.

This fixes a regression introduced by
commit 0d2e778e38
"net: phy: replace PHY_HAS_INTERRUPT with a check for
config_intr and ack_interrupt".
This assumes that a PHY cannot trigger interrupt unless
it has .config_intr() or .ack_interrupt() implemented.
A later patch makes the code assume both need to be
implemented for interrupts to be present.
But this PHY (which is inside a DSA) will happily
fire interrupts without either callback.
Implement dummy callbacks for .config_intr() and
.ack_interrupt() in the phy header to fix this.
Tested on the RTL8366RB on D-Link DIR-685.

bridge. If we do not add the port which recives query with source
0.0.0.0 to router list, the IGMP reports will not be about to forward

Just like commit e2ba732a16 ("selftests: fib_tests: sleep after

There are two sets of carrier tests. The first slept after the carrier
was set to off, and when the second set ran, it was likely that the
linkwatch would be able to run again without much delay, reducing the
likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a
loop, you will quickly notice the failures.
Sleeping on the second set of tests make the failures go away.

- Use hrtimer_try_to_cancel() instead of hrtimer_cancel() in the
PM-runtime framework to avoid a possible timer-related deadlock
introduced recently (Vincent Guittot).
- Reorder the scmi-cpufreq driver code to avoid accessing memory
that has just been freed (Yangtao Li).

We recently created a bpf@vger.kernel.org list (https://lore.kernel.org/bpf/)
for BPF related discussions, originally in context of BPF track at LSF/MM
for topic discussions. It's *optional* but *desirable* to keep it in Cc for
BPF related kernel/loader/llvm/tooling threads, meaning also infrastructure
like llvm that sits on top of kernel but is crucial to BPF. In any case,
netdev with it's bpf delegate is *as-is* today primary list for patches, so
nothing changes in the workflow. Main purpose is to have some more awareness
for the bpf@vger.kernel.org list that folks can Cc for BPF specific topics.
