[GIT PULL] vfs fixes

[Christian Brauner]

Hey Linus,

/* Summary */
This contains a few fixes:

VFS:

- Fix copy_page_from_iter_atomic() if KMAP_LOCAL_FORCE_MAP=y is set.

- Add a get_tree_bdev_flags() helper that allows to modify e.g., whether
  errors are logged into the filesystem context during superblock
  creation. This is used by erofs to fix a userspace regression where an
  error is currently logged when its used on a regular file which is an
  new allowed mode in erofs.

netfs:

- Fix the sysfs debug path in the documentation.

- Fix iov_iter_get_pages*() for folio queues by skipping the page
  extracation if we're at the end of a folio.

afs:

- Fix moving subdirectories to different parent directory.

autofs:

- Fix handling of AUTOFS_DEV_IOCTL_TIMEOUT_CMD ioctl in
  validate_dev_ioctl(). The actual ioctl number, not the ioctl command
  needs to be checked for autofs.

/* Testing */
