This is called CANCELGRANT after the\nstatus code sent to the callback. fs/dlm does not provide this\ncallback, so dlmglue must be changed to live without it.\no2dlm_unlock_ast_wrapper() in stackglue now ignores CANCELGRANT calls.\n\nBecause dlmglue no longer sees CANCELGRANT, ocfs2_unlock_ast() no longer\nneeds to check for it. ocfs2_locking_ast() must catch that a cancel was\ntried and clear the cancel state.\n\nMaking these changes opens up a locking race. dlmglue uses the the\nOCFS2_LOCK_BUSY flag to ensure only one thread is calling the dlm at any\none time. But dlmglue must unlock the lockres before calling into the\ndlm. In the small window of time between unlocking the lockres and\ncalling the dlm, the downconvert thread can try to cancel the lock. The\ndownconvert thread is checking the OCFS2_LOCK_BUSY flag - it doesn\u0027t\nknow that ocfs2_dlm_lock() has not yet been called.\n\nBecause ocfs2_dlm_lock() has not yet been called, the cancel operation\nwill just be a no-op. There\u0027s nothing to cancel. With CANCELGRANT,\ndlmglue uses the CANCELGRANT callback to clear up the cancel state.\nWhen it comes around again, it will retry the cancel. Eventually, the\nfirst thread will have called into ocfs2_dlm_lock(), and either the\nlock or the cancel will succeed. The downconvert thread can then do its\ndownconvert.\n\nWithout CANCELGRANT, there is nothing to clean up the cancellation\nstate. The downconvert thread does not know to retry its operations.\nMore importantly, the original lock may be blocking on the other node\nthat is trying to cancel us. With neither able to make progress, the\nast is never called and the cancellation state is never cleaned up that\nway. dlmglue is deadlocked.\n\nThe OCFS2_LOCK_PENDING flag is introduced to remedy this window. It is\nset at the same time OCFS2_LOCK_BUSY is. Thus, the downconvert thread\ncan check whether the lock is cancelable. If not, it just loops around\nto try again. Once ocfs2_dlm_lock() is called, the thread then clears\nOCFS2_LOCK_PENDING and wakes the downconvert thread. Now, if the\ndownconvert thread finds the lock BUSY, it can safely try to cancel it.\nWhether the cancel works or not, the state will be properly set and the\nlock processing can continue.\n\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\nSigned-off-by: Mark Fasheh \u003cmfasheh@suse.com\u003e\n" }, { "commit": "6953b4c008628b945bfe0cee97f6e78a98773859", "tree": "de00a19f59466d9e83b00112696afa5b02abbd9c", "parents": [ "19fdb624dc8ccb663f6e48b3a3a3fa4e4e567fc1" ], "author": { "name": "Joel Becker", "email": "joel.becker@oracle.com", "time": "Tue Jan 29 16:59:56 2008 -0800" }, "committer": { "name": "Mark Fasheh", "email": "mfasheh@suse.com", "time": "Fri Apr 18 08:56:04 2008 -0700" }, "message": "ocfs2: Move o2hb functionality into the stack glue.\n\nThe last bit of classic stack used directly in ocfs2 code is o2hb.\nSpecifically, the check for heartbeat during mount and the call to\nocfs2_hb_ctl during unmount.\n\nWe create an extra API, ocfs2_cluster_hangup(), to encapsulate the call\nto ocfs2_hb_ctl.
