    ocfs2: Fixup orphan scan cleanup after failed mount

    If the mount fails for any reason, ocfs2_dismount_volume calls
    ocfs2_orphan_scan_stop. It requires that ocfs2_orphan_scan_init
    be called to setup the mutex and work queues, but that doesn't
    happen if the mount has failed and we oops accessing an uninitialized
    work queue.

    This patch splits the init and startup of the orphan scan, eliminating
    the oops.

    [This patch was pulled from ocfs2.git before it hit the mainline.]

    ocfs2: Do not initialize lvb in ocfs2_orphan_scan_lock_res_init()

    Mainline commit 3211949f8998dde71d9fe2e063de045ece5e0473

    We don't access the LVB in our ocfs2_*_lock_res_init() functions.

    Since the LVB can become invalid during some cluster recovery
    operations, the dlmglue must be able to handle an uninitialized
    LVB.

    For the orphan scan lock, we initialized an uninitialzed LVB with our
    scan sequence number plus one.  This starts a normal orphan scan
    cycle.

    ocfs2: Stop orphan scan as early as possible during umount

    Mainline commit 692684e19e317a374c18e70a44d6413e51f71c11

    Currently if the orphan scan fires a tick before the user issues the umount,
    the umount will wait for the queued orphan scan tasks to complete.

    This patch makes the umount stop the orphan scan as early as possible so as
    to reduce the probability of the queued tasks slowing down the umount.

    ocfs2: Update atime in splice read if necessary.

    Mainline commit 1962f39abbb2d5643a7d59169422661a2d58793d

    We should call ocfs2_inode_lock_atime instead of ocfs2_inode_lock
    in ocfs2_file_splice_read like we do in ocfs2_file_aio_read so
    that we can update atime in splice read if necessary.
