51d0de7596 rust: platform: require Send for Driver trait implementers
The instance of Self, returned and created by Driver::probe() is
dropped in the bus' remove() callback.

Request implementers of the Driver trait to implement Send, since the
remove() callback is not guaranteed to run from the same thread as
probe().

Merge patch series "pidfs: handle multi-threaded exec and premature thread-group leader exit"
Christian Brauner <brauner@kernel.org> says:

This is another attempt at trying to make pidfd polling for
multi-threaded exec and premature thread-group leader exit consistent.

A quick recap of these two cases:

(1) During a multi-threaded exec by a subthread, i.e., non-thread-group
    leader thread, all other threads in the thread-group including the
    thread-group leader are killed and the struct pid of the
    thread-group leader will be taken over by the subthread that called
    exec. IOW, two tasks change their TIDs.

(2) A premature thread-group leader exit means that the thread-group
    leader exited before all of the other subthreads in the thread-group
    have exited.

Both cases lead to inconsistencies for pidfd polling with PIDFD_THREAD.
Any caller that holds a PIDFD_THREAD pidfd to the current thread-group
leader may or may not see an exit notification on the file descriptor
depending on when poll is performed. If the poll is performed before the
exec of the subthread has concluded an exit notification is generated
for the old thread-group leader. If the poll is performed after the exec
of the subthread has concluded no exit notification is generated for the
old thread-group leader.

The correct behavior would be to simply not generate an exit
notification on the struct pid of a subhthread exec because the struct
pid is taken over by the subthread and thus remains alive.

But this is difficult to handle because a thread-group may exit
premature as mentioned in (2). In that case an exit notification is
reliably generated but the subthreads may continue to run for an
indeterminate amount of time and thus also may exec at some point.

This tiny series tries to address this problem. If that works correctly
then no exit notifications are generated for a PIDFD_THREAD pidfd for a
thread-group leader until all subthreads have been reaped. If a
subthread should exec before no exit notification will be generated
until that task exits or it creates subthreads and repeates the cycle.

PIDFD_THREAD notification on premature thread-group leader exit.

fs: sort out fd allocation vs dup2 race commentary, take 2
fd_install() has a questionable comment above it.

While it correctly points out a possible race against dup2(), it states:
> We need to detect this and fput() the struct file we are about to
> overwrite in this case.
>
> It should never happen - if we allow dup2() do it, _really_ bad things
> will follow.

I have difficulty parsing the above. The first sentence would suggest
fd_install() tries to detect and recover from the race (it does not),
the next one claims the race needs to be dealt with (it is, by dup2()).

Given that fd_install() does not suffer the burden, this patch removes
the above and instead expands on the race in dup2() commentary.

While here tidy up the docs around fd_install().

Merge patch series "further iomap large atomic writes changes"
John Garry <john.g.garry@oracle.com> says:

These iomap changes are spun-off the XFS large atomic writes series at
https://lore.kernel.org/linux-xfs/86a64256-497a-453b-bbba-a5ac6b4cb056@oracle.com/T/#ma99c763221de9d49ea2ccfca9ff9b8d71c8b2677

The XFS parts there are not ready yet, but it is worth having the iomap
changes queued in advance.

Some much earlier changes from that same series were already queued in the
vfs tree, and these patches rework those changes - specifically the
first patch in this series does.

The most other significant change is the patch to rework how the bio flags
are set in the DIO patch.

iomap: rework IOMAP atomic flags
Flag IOMAP_ATOMIC_SW is not really required. The idea of having this flag
is that the FS ->iomap_begin callback could check if this flag is set to
decide whether to do a SW (FS-based) atomic write. But the FS can set
which ->iomap_begin callback it wants when deciding to do a FS-based
atomic write.

Furthermore, it was thought that IOMAP_ATOMIC_HW is not a proper name, as
the block driver can use SW-methods to emulate an atomic write. So change
back to IOMAP_ATOMIC.

The ->iomap_begin callback needs though to indicate to iomap core that
REQ_ATOMIC needs to be set, so add IOMAP_F_ATOMIC_BIO for that.

These changes were suggested by Christoph Hellwig and Dave Chinner.

2c1f97a52c mptcp: Fix data stream corruption in the address announcement
Because of the size restriction in the TCP options space, the MPTCP
ADD_ADDR option is exclusive and cannot be sent with other MPTCP ones.
For this reason, in the linked mptcp_out_options structure, group of
fields linked to different options are part of the same union.

There is a case where the mptcp_pm_add_addr_signal() function can modify
opts->addr, but not ended up sending an ADD_ADDR. Later on, back in
mptcp_established_options, other options will be sent, but with
unexpected data written in other fields due to the union, e.g. in
opts->ext_copy. This could lead to a data stream corruption in the next
packet.

Using an intermediate variable, prevents from corrupting previously
established DSS option. The assignment of the ADD_ADDR option
parameters is now done once we are sure this ADD_ADDR option can be set
in the packet, e.g. after having dropped other suboptions.

do the necessary checks before calling kthread_stop to avoid a crash.

96622d58f5 staging: vchiq_arm: Don't use %pK through printk
In the past %pK was preferable to %p as it would not leak raw pointer
values into the kernel log.
Since commit ad67b74d24 ("printk: hash addresses printed with %p")
the regular %p has been improved to avoid this issue.
Furthermore, restricted pointers ("%pK") were never meant to be used
through printk(). They can still unintentionally leak raw pointers or
acquire sleeping looks in atomic contexts.

Switch to the regular pointer formatting which is safer and
easier to reason about.
There are still a few users of %pK left, but these use it through seq_file,
for which its usage is safe.

ed3751860e staging: gpib: change return type of t1_delay function to report errors
The current code returns "unsigned int" and it doesn't handle errors
correctly if it happens during ioctl call for t1 delay configuration.

The ni_usb_t1_delay(), from NI, is the only function returning -1
at this point. The caller, t1_delay_ioctl(), doesn't check for errors
and sets board->t1_nano_sec to -1 and returns success.
The board->t1_nano_sec value is also used in ni_usb_setup_t1_delay()
besides the ioctl call and a value of -1 is treated as being above 1100ns.
It may or may not have a noticeable effect, but it's obviously not right
considering the content of ni_usb_setup_t1_delay().

Typical delays are in the 200-2000 range, but definitely not more
than INT_MAX so we can fix this code by changing the return type to int
and adding a check for errors. While we're at it, lets change the error
code in ni_usb_t1_delay() from -1 and instead propagate the error from
ni_usb_write_registers().

31e75ed964 mmc: host: Wait for Vdd to settle on card power off
The SD spec version 6.0 section 6.4.1.5 requires that Vdd must be
lowered to less than 0.5V for a minimum of 1 ms when powering off a
card. Increase wait to 15 ms so that voltage has time to drain down
to 0.5V and cards can power off correctly. Issues with voltage drain
time were only observed on Apollo Lake and Bay Trail host controllers
so this fix is limited to those devices.
