| * | [S390] cio/crw: add/fix locking | Heiko Carstens | 2009-03-26 | 1 | -9/+23 |
| | | | | | | | | | | | | | | | | The crw_unregister_handler uses xchg + synchronize_sched when unregistering a crw_handler. This doesn't protect crw_collect_info to potentially jump to NULL since it has unlocked code like this: if (crw_handlers[i]) crw_handlers[i](NULL, NULL, 1); So add a mutex which protects the crw handler array for changes.
