[GIT PULL for v6.7] autofs updates

[Christian Brauner]

Hey Linus,

/* Summary */
This ports autofs to the new mount api. The patchset has existed for
quite a while but never made it upstream. Ian picked it back up.

This also fixes a bug where fs_param_is_fd() was passed a garbage
param->dirfd but it expected it to be set to the fd that was used to set
param->file otherwise result->uint_32 contains nonsense. So make sure
it's set.

One less filesystem using the old mount api. We're getting there, albeit
rather slow. The last remaining major filesystem that hasn't converted
is btrfs. Patches exist - I even wrote them - but so far they haven't
made it upstream.

/* Testing */
clang: Debian clang version 16.0.6 (16)
gcc: gcc (Debian 13.2.0-5) 13.2.0

All patches are based on v6.6-rc2 and have been sitting in linux-next.
No build failures or warnings were observed.

/* Conflicts */
At the time of creating this PR no merge conflicts were reported from
linux-next and no merge conflicts showed up doing a test-merge with
current mainline.
