xuejiufei 32e493265b ocfs2/dlm: do not insert a new mle when another process is already migrating ... When two processes are migrating the same lockres, dlm_add_migration_mle() return -EEXIST, but insert a new mle in hash list. dlm_migrate_lockres() will detach the old mle and free the new one which is already in hash list, that will destroy the list.
