[GIT PULL] vfs fixes

[Christian Brauner]

Hey Linus,

/* Summary */

This contains various fixes for this cycle:

- Add a new maintainer for configfs.

- Fix exportfs module description.

- Place flexible array memeber at the end of an internal struct in the
  mount code.

- Add new maintainer for netfslib as Jeff Layton is stepping down as
  current co-maintainer.

- Fix error handling in cachefiles_get_directory().

- Cleanup do_notify_pidfd().

- Fix syscall number definitions in pidfd selftests.

- Fix racy usage of fs_struct->in exec during multi-threaded exec.

- Ensure correct exit code is reported when pidfs_exit() is called from
  release_task() for a delayed thread-group leader exit.

- Fix conflicting iomap flag definitions.
