Joseph Qi 1e58958160 ocfs2/dlm: fix race between dispatched_work and dlm_lockres_grab_inflight_worker ... Commit ac4fef4d23 ("ocfs2/dlm: do not purge lockres that is queued for assert master") may have the following possible race case: dlm_dispatch_assert_master dlm_wq ======================================================================== queue_work(dlm->quedlm_worker, &dlm->dispatched_work); dispatch work, dlm_lockres_drop_inflight_worker *BUG_ON(res->inflight_assert_workers == 0)* dlm_lockres_grab_inflight_worker inflight_assert_workers++ So ensure inflight_assert_workers to be increased first.
