  "message": "ocfs2 fix o2dlm dlm run purgelist (rev 3)\n\nThis patch fixes two problems in dlm_run_purgelist\n\n1. If a lockres is found to be in use, dlm_run_purgelist keeps trying to purge\nthe same lockres instead of trying the next lockres.\n\n2. When a lockres is found unused, dlm_run_purgelist releases lockres spinlock\nbefore setting DLM_LOCK_RES_DROPPING_REF and calls dlm_purge_lockres.\nspinlock is reacquired but in this window lockres can get reused. This leads\nto BUG.\n\nThis patch modifies dlm_run_purgelist to skip lockres if it\u0027s in use and purge\n next lockres. It also sets DLM_LOCK_RES_DROPPING_REF before releasing the\nlockres spinlock protecting it from getting reused.\n\nSigned-off-by: Srinivas Eeda \u003csrinivas.eeda@oracle.com\u003e\nAcked-by: Sunil Mushran \u003csunil.mushran@oracle.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Joel Becker \u003cjoel.becker@oracle.com\u003e\n",
