* ocfs2: Allow binary names in the DLMMark Fasheh2006-09-24
| | | | | | | | The OCFS2 DLM uses strlen() to determine lock name length, which excludes the possibility of putting binary values in the name string. Fix this by requiring that string length be passed in as a parameter. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* [PATCH] fs/ocfs2/dlm/dlmrecovery.c: make dlm_lockres_master_requery() staticAdrian Bunk2006-06-29
| | | | | | | dlm_lockres_master_requery() became global without any external usage. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* [PATCH] spin/rwlock init cleanupsIngo Molnar2006-06-27
| | | | | | | | | | | | | | | | | | | | | locking init cleanups: - convert " = SPIN_LOCK_UNLOCKED" to spin_lock_init() or DEFINE_SPINLOCK() - convert rwlocks in a similar manner this patch was generated automatically. Motivation: - cleanliness - lockdep needs control of lock initialization, which the open-coded variants do not give - it's also useful for -rt and for lock debugging in general Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] fs/ocfs2/dlm/: cleanupsAdrian Bunk2006-06-26
| | | | | | | | | | | | This patch #if 0's the no longer used dlm_dump_lock_resources(). Since this makes dlmdebug.h empty, this patch also removes this header. Additionally, the needlessly global dlm_is_node_recovered() is made static. Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

* ocfs2: dlm_remaster_locks() should never exit without completingKurt Hackel2006-06-26
| | | | | | | | | We cannot restart recovery. Once we begin to recover a node, keep the state of the recovery intact and follow through, regardless of any other node deaths that may occur. Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>
* ocfs2: special case recovery lock in dlmlock_remote()Kurt Hackel2006-06-26
| | | | | | | | | | If the previous master of the recovery lock dies, let calc_usage take it down completely and let the caller completely redo the dlmlock() call. Otherwise, there will never be an opportunity to re-master the lockres and recovery wont be able to progress.

* [PATCH] ocfs2: dlm recovery fixesKurt Hackel2006-03-24
| | | | | | | | | | when starting lock mastery (excepting the recovery lock) wait on any nodes needing recovery. fix one instance where lock resources were left attached to the recovery list after recovery completed. ensure that the node_down code is run uniformly regardless of which node found the dead node first.

* [PATCH] ocfs2: use hlists for lockres hashMark Fasheh2006-03-01

* [PATCH] ocfs2: add dlm_wait_for_node_deathKurt Hackel2006-02-16
| | | | | | | | | | * add dlm_wait_for_node_death function to be used after receiving a network error. this will wait for the given timeout to allow the heartbeat callbacks to update the domain map. without this, some paths may spin and consume enough cpu that the heartbeat gets starved and never updates.

* [PATCH] OCFS2: The Second Oracle Cluster FilesystemKurt Hackel2006-01-03
A distributed lock manager built with the cluster file system use case in mind. The OCFS2 dlm exposes a VMS style API, though things have been simplified internally. The only lock levels implemented currently are NLMODE, PRMODE and EXMODE. Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com> Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com>
