[GIT PULL] vfs fixes

[Christian Brauner]

Hey Linus,

/* Summary */
This contains a few fixes:

* Fix a memory leak in cachefiles.
* Restrict aio cancellations to I/O submitted through the aio interfaces as
  this is otherwise causing issues for I/O submitted via io_uring.
* Increase buffer for afs volume status to avoid overflow.
* Fix a missing zero-length check in unbuffered writes in the netfs library.
  If generic_write_checks() returns zero make netfs_unbuffered_write_iter()
  return right away.
* Prevent a leak in i_dio_count caused by netfs_begin_read() operaing pas
  i_size. It will return early and leave i_dio_count incremented.
* Account for ipv4 addresses as well ass ipv6 addresses when processing
  incoming callbacks in afs.

/* Testing */
