  "message": "dlm: fixes for nodir mode\n\nThe \"nodir\" mode (statically assign master nodes instead\nof using the resource directory) has always been highly\nexperimental, and never seriously used.  This commit\nfixes a number of problems, making nodir much more usable.\n\n- Major change to recovery: recover all locks and restart\n  all in-progress operations after recovery.  In some\n  cases it\u0027s not possible to know which in-progess locks\n  to recover, so recover all.  (Most require recovery\n  in nodir mode anyway since rehashing changes most\n  master nodes.)\n\n- Change the way nodir mode is enabled, from a command\n  line mount arg passed through gfs2, into a sysfs\n  file managed by dlm_controld, consistent with the\n  other config settings.\n\n- Allow recovering MSTCPY locks on an rsb that has not\n  yet been turned into a master copy.\n\n- Ignore RCOM_LOCK and RCOM_LOCK_REPLY recovery messages\n  from a previous, aborted recovery cycle.  Base this\n  on the local recovery status not being in the state\n  where any nodes should be sending LOCK messages for the\n  current recovery cycle.\n\n- Hold rsb lock around dlm_purge_mstcpy_locks() because it\n  may run concurrently with dlm_recover_master_copy().\n\n- Maintain highbast on process-copy lkb\u0027s (in addition to\n  the master as is usual), because the lkb can switch\n  back and forth between being a master and being a\n  process copy as the master node changes in recovery.\n\n- When recovering MSTCPY locks, flag rsb\u0027s that have\n  non-empty convert or waiting queues for granting\n  at the end of recovery.  (Rename flag from LOCKS_PURGED\n  to RECOVER_GRANT and similar for the recovery function,\n  because it\u0027s not only resources with purged locks\n  that need grant a grant attempt.)\n\n- Replace a couple of unnecessary assertion panics with\n  error messages.\n\nSigned-off-by: David Teigland \u003cteigland@redhat.com\u003e\n",
