  • d4400156d   [DLM] fix requestqueue race ... Browse Code »

    Red Hat BZ 211914

    There's a race between dlm_recoverd (1) enabling locking and (2) clearing
    out the requestqueue, and dlm_recvd (1) checking if locking is enabled and
    (2) adding a message to the requestqueue. An order of recoverd(1),
    recvd(1), recvd(2), recoverd(2) will result in a message being left on the
    requestqueue. The fix is to have dlm_recvd check if dlm_recoverd has
    enabled locking after taking the mutex for the requestqueue and if it has
    processing the message instead of queueing it.

  • e7fd41792   [DLM] The core of the DLM for GFS2/CLVM ... Browse Code »

    This is the core of the distributed lock manager which is required
    to use GFS2 as a cluster filesystem. It is also used by CLVM and
    can be used as a standalone lock manager independantly of either
    of these two projects.

    It implements VAX-style locking modes.
