Merge tag 'vfs-6.13.exportfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs exportfs updates from Christian Brauner:
 "This contains work to bring NFS connectable file handles to userspace
  servers.

  The name_to_handle_at() system call is extended to encode connectable
  file handles. Such file handles can be resolved to an open file with a
  connected path. So far userspace NFS servers couldn't make use of this
  functionality even though the kernel does already support it. This is
  achieved by introducing a new flag for name_to_handle_at().

  Similarly, the open_by_handle_at() system call is tought to understand
  connectable file handles explicitly created via name_to_handle_at()"

* tag 'vfs-6.13.exportfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  fs: open_by_handle_at() support for decoding "explicit connectable" file handles
  fs: name_to_handle_at() support for "explicit connectable" file handles
  fs: prepare for "explicit connectable" file handles
