[GIT PULL] vfs exportfs

[Christian Brauner]

Hey Linus,

/* Summary */
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().

/* Testing */

gcc version 14.2.0 (Debian 14.2.0-6)
Debian clang version 16.0.6 (27+b1)

All patches are based on v6.12-rc3 and have been sitting in linux-next.
No build failures or warnings were observed.
