...e two problems in dlm_run_purgelist 1. If a lockres is found to be in use, dlm_run_purgelist keeps trying to purge the same lockres instead of trying the next lockres. 2. When a lockres is found unused, dlm_run_purgelist releases lockres spinlock before setting DLM_LOCK_RES_DROPPING_REF and calls dlm_purge_lockres. spinlock is reacquired but in this window lockres can get reused. This leads to BUG. This patch modifies dlm_run_purgelist to skip lockres if it's in use and purge next lockres. It also sets DLM_LOCK_RES_DROPPING_REF before releasing the lockres spinlock protecting it from getting reused. S...

Found 15 patches (out of 162) that appeared relevant to ocfs2 1.4. Please review. Sunil

Please review the list of patches being applied to the ocfs2 1.4 tree. All patches list the mainline commit hash. Thanks Sunil

The changes from the last drop are: 1. Patch 11 removes struct dlm_lock_name. 2. Patch 12 is an unrelated bugfix. Actually is related to a bugfix that we are retracting in mainline currently. The patch may need more testing. While I did hit the condition in my testing, Marcos hasn't. I am sending it because it can be queued for 2.6.30. Give us more time to test. 3. Patch 13 will be useful
