| H A D | lockmgr.h | diff 161337 Tue Aug 15 16:29:01 MDT 2006 jhb Add a new 'show sleepchain' ddb command similar to 'show lockchain' except that it operates on lockmgr and sx locks. This can be useful for tracking down vnode deadlocks in VFS for example. Note that this command is a bit more fragile than 'show lockchain' as we have to poke around at the wait channel of a thread to see if it points to either a struct lock or a condition variable inside of a struct sx. If td_wchan points to something unmapped, then this command will terminate early due to a fault, but no harm will be done. |
