| 58 | 58 | Each thread contains - besides the ''busylocks'' counter - an optional ''busylocks_root'' field, that is the root of the embedded xlist of (local or remote) busylocks hold by a given thread at a given time. This list is implemented by an optional ''xlist'' field in the busy lock descriptor. It is dynamically updated by the ''busylock_acquire()'' and ''busylock_release()'' functions. The set of taken busylocks is printed in the error message, when the scheduler detects that a descheduling thread is holding one or several busylocks. This list can also be be printed through the ''idbg'' interactive debugger, for any thread identified by its (pid,trdid). |
