Pull vfs fixes from Christian Brauner:

 - When allocating pages for a watch queue failed, we didn't return an
   error causing userspace to proceed even though all subsequent
   notifcations would be lost. Make sure to return an error.

 - Fix a misformed tree entry for the idmapping maintainers entry.

 - When setting file leases from an idmapped mount via
   generic_setlease() we need to take the idmapping into account
   otherwise taking a lease would fail from an idmapped mount.

 - Remove two redundant assignments, one in splice code and the other in
   locks code, that static checkers complained about.

The cpumask_check() was unnecessarily tight, and causes problems for the
users of cpumask_next().

We have a number of users that take the previous return value of one of
the bit scanning functions and subtract one to keep it in "range".  But
since the scanning functions end up returning up to 'small_cpumask_bits'
instead of the tighter 'nr_cpumask_bits', the range really needs to be
using that widened form.

[ This "previous-1" behavior is also the reason we have all those
  comments about /* -1 is a legal arg here. */ and separate checks for
  that being ok.  So we could have just made "small_cpumask_bits-1"
  be a similar special "don't check this" value.

  Tetsuo Handa even suggested a patch that only does that for
  cpumask_next(), since that seems to be the only actual case that
  triggers, but that all makes it even _more_ magical and special. So
  just relax the check ]

One example of this kind of pattern being the 'c_start()' function in
arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on
other architectures.

If the boot loader inode has never been used before, the
EXT4_IOC_SWAP_BOOT inode will initialize it, including setting the
i_size to 0.  However, if the "never before used" boot loader has a
non-zero i_size, then i_disksize will be non-zero, and the
inconsistency between i_size and i_disksize can trigger a kernel

Pull io_uring fixes from Jens Axboe:

 - Stop setting PF_NO_SETAFFINITY on io-wq workers.

   This has been reported in the past as it confuses some applications,
   as some of their threads will fail with -1/EINVAL if attempted
   affinitized. Most recent report was on cpusets, where enabling that
   with io-wq workers active will fail.

   Just deal with the mask changing by checking when a worker times out,
   and then exit if we have no work pending.

 - Fix an issue with passthrough support where we don't properly check
   if the file type has pollable uring_cmd support.

 - Fix a reported W=1 warning on a variable being set and unused. Add a
   special helper for iterating these lists that doesn't save the
   previous list element, if that iterator never ends up using it.

We're currently using stop_machine() to update ftrace & kprobes, which
means that the thread that takes text_mutex during may not be the same
as the thread that eventually patches the code.  This isn't actually a
race because the lock is still held (preventing any other concurrent
accesses) and there is only one thread running during stop_machine(),
but it does trigger a lockdep failure.

This patch just elides the lockdep check during stop_machine.

The i2cdev_{at,de}tach_adapter() callbacks are used for two purposes:
  1. As notifier callbacks, when (un)registering I2C adapters created or
     destroyed after i2c_dev_init(),
  2. As bus iterator callbacks, for registering already existing
     adapters from i2c_dev_init(), and for cleanup.

Unfortunately both use cases expect different return values: the former
expects NOTIFY_* return codes, while the latter expects zero or error
codes, and aborts in case of error.

Hence in case 2, as soon as i2cdev_{at,de}tach_adapter() returns
(non-zero) NOTIFY_OK, the bus iterator aborts.  This causes (a) only the
first already existing adapter to be registered, leading to missing
/dev/i2c-* entries, and (b) a failure to unregister all but the first
I2C adapter during cleanup.

Fix this by introducing separate callbacks for the bus iterator,
wrapping the notifier functions, and always returning succes.
Any errors inside these callback functions are unlikely to happen, and
are fatal anyway.

Commit b8a1a4cd ("i2c: Provide a temporary .probe_new() call-back
type") introduced a new probe callback to convert i2c init routines to
not take an i2c_device_id parameter. Now that all in-tree drivers are
converted to the temporary .probe_new() callback, .probe() can be
modified to match the desired prototype.

Now that .probe() and .probe_new() have the same semantic, they can be
defined as members of an anonymous union to save some memory and
simplify the core code a bit.
