    afs: afsd -shutdown sets afs_cold_shutdown too soon
    'afsd -shutdown' always invokes syscall(AFSOP_SHUTDOWN)
    with parm2 set to 1 to indicate a "cold" shutdown.
    (There are no other callers to AFSOP_SHUTDOWN).
    AFSOP_SHUTDOWN sets global variable afs_cold_shutdown
    based on the value of parm2.  Then it checks to see if
    AFS is still mounted; if so, we return early with EACCES.
    However, global afs_cold_shutdown remains set.
    Therefore, the next successful 'umount' after a "failed"
    'afsd -shutdown' will always trigger a "cold" shutdown.
    This is contrary to the intent of the current implementation,
    which is to perform a "warm" shutdown upon 'umount' for
    most platforms.  (Exceptions:  AIX, OBSD, NBSD always
    specify a cold shutdown upon 'umount').
    This bug would never be noticed on the "cold" exception
    platforms, but on the "warm" platforms the inconsistency
    of seeing an unexpected "COLD" shutdown may be confusing
    and surprising.
    Make shutdown operation more self-consistent by modifying
    AFSOP_SHUTDOWN to defer setting of afs_cold_shutdown until
    after the mount test.
