  move mount-related externs from fs.h to mount.h (2022-05-19 23:25:48 -0400)

----------------------------------------------------------------
	Cleanups (and one fix) around struct mount handling.
The fix is usermode_driver.c one - once you've done kern_mount(), you
must kern_unmount(); simple mntput() will end up with a leak.  Several
failure exits in there messed up that way...  In practice you won't
hit those particular failure exits without fault injection, though.

----------------------------------------------------------------
Al Viro (5):
      uninline may_mount() and don't opencode it in fspick(2)/fsopen(2)
      linux/mount.h: trim includes
      m->mnt_root->d_inode->i_sb is a weird way to spell m->mnt_sb...
      blob_to_mnt(): kern_unmount() is needed to undo kern_mount()
      move mount-related externs from fs.h to mount.h
