Subject: [GIT PULL] vfs fixes

/* Summary */

This contains a final set of fixes for this cycle:

VFS:

- Ensure that the stable offset api doesn't return duplicate directory
  entries when userspace has to perform the getdents call multiple times
  on large directories.

afs:

- Prevent invalid pointer dereference during get_link RCU pathwalk.

fuse:

- Fix deadlock caused by uninitialized rings when using io_uring with fuse.

- Handle race condition when using io_uring with fuse to prevent NULL dereference.

libnetfs:

- Ensure that invalidate_cache is only called if implemented.

- Fix collection of results during pause when collection is offloaded.

- Ensure rolling_buffer_load_from_ra() doesn't clear mark bits.

- Make netfs_unbuffered_read() return ssize_t rather than int.
