  • These externs belong in fs/internal.h. Rename (they are not acct-specific
    anymore) and move them over there.

  • Add a new field to fs_pin - kill(pin). That's what umount and r/o remount
    will be calling for all pins attached to vfsmount and superblock resp.
    Called after bumping the refcount, so it won't go away under us. Dropping
    the refcount is responsibility of the instance. All generic stuff moved to
    fs/fs_pin.c; the next step will rip all the knowledge of kernel/acct.c from
    fs/super.c and fs/namespace.c. After that - death to mnt_pin(); it was
    intended to be usable as generic mechanism for code that wants to attach
    objects to vfsmount, so that they would not make the sucker busy and
    would get killed on umount. Never got it right; it remained acct.c-specific
    all along. Now it's very close to being killable.
