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

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"

* tag 'vfs-6.15-rc1.mount.api' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs:
  sysv: convert sysv to use the new mount api
  vfs: remove some unused old mount api code
  devtmpfs: replace ->mount with ->get_tree in public instance
  vfs: Convert devpts to use the new mount API
