xuejiufei cc28d6d80f ocfs2/dlm: clear migration_pending when migration target goes down ... We have found a BUG on res->migration_pending when migrating lock resources. The situation is as follows. dlm_mark_lockres_migration res->migration_pending = 1; __dlm_lockres_reserve_ast dlm_lockres_release_ast returns with res->migration_pending remains because other threads reserve asts wait dlm_migration_can_proceed returns 1 >>>>>>> o2hb found that target goes down and remove target from domain_map dlm_migration_can_proceed returns 1 dlm_mark_lockres_migrating returns -ESHOTDOWN with res->migration_pending still remains. When reentering dlm_mark_lockres_migrating(), it will trigger the BUG_ON with res->migration_pending. So clear migration_pending when target is down.
