Merge tag 'vfs-6.15-rc1.mount.api' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs

Pull vfs mount API updates from Christian Brauner:
 "This converts the remaining pseudo filesystems to the new mount api.

  The sysv conversion is a bit gratuitous because we remove sysv in
  another pull request. But if we have to revert the removal we at least
  will have it converted to the new mount api already"
