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
