The tag, ocfs2-1.4.11 has been created at e2515e851c8a936a831ff611e8f741904cc9e1e6 (commit) - Log ----------------------------------------------------------------- commit e2515e851c8a936a831ff611e8f741904cc9e1e6 Author: Srinivas Eeda Date: Wed Nov 12 23:23:08 2014 -0800 o2dlm: fix a race between purge and master query Node A sends a master query request to node B which is the master. At this lockres happens to be on purgelist. dlm_master_request_handler gets the dlm spinlock, finds the resource and releases the dlm spin lock. Right at this dlm_thread on this node could purge the lockres. dlm_master_request_handler can then acquire lockres spinlock and reply to Node A that node B is the master even though lockres on node B is purged. The above scenario will now make node B falsely think node A is the master.
