[GIT PULL] dlm updates for 3.6
Hi Linus, Please pull dlm updates from tag: git://git.kernel.org/pub/scm/linux/kernel/git/teigland/linux-dlm.git dlm-3.6 This set includes a major redesign of recording the master node for resources. The old dir hash table, which just held the master node for each resource, has been removed. The rsb hash table has always duplicated the master node value from the dir, and is now the single record of it. Having two full hash tables of all resources has always been a waste, especially since one just duplicated a single value from the other. Local requests will now often require one instead of two lengthy hash table searches. The other substantial change is made possible by the dirtbl removal, and fixes a long standing race between resource removal and lookup by reworking how removal is done. At the same time it improves the efficiency of removal by avoiding repeated searches through a hash bucket. The other commits include minor fixes and changes. Thanks, Dave David Teigland (6): dlm: use rsbtbl as resource directory dlm: use idr instead of list for recovered rsbs dlm: fix race between remove and lookup dlm: use wait_event_timeout dlm: fix conversion deadlock from recovery dlm: fix missing dir remove fs/dlm/config.c |7 - fs/dlm/config.h |1 - fs/dlm/debug_fs.c | 103 +++- fs/dlm/dir.c | 287 +++ fs/dlm/dir.h |7 +- fs/dlm/dlm_internal.h | 62 ++- fs/dlm/lock.c | 1292 - fs/dlm/lock.h |5 +- fs/dlm/lockspace.c| 45 +- fs/dlm/rcom.c | 147 -- fs/dlm/rcom.h |1 + fs/dlm/recover.c | 295 +++ fs/dlm/recover.h |2 +- fs/dlm/recoverd.c | 14 +- 14 files changed, 1600 insertions(+), 668 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
