[Beignet] [PATCH 3/9] Delete all the verbose locks and use list to store CL objects.
junyan.he at inbox.com
junyan.he at inbox.com
Tue Aug 2 11:38:50 UTC 2016
From: Junyan He <junyan.he at intel.com>
We use context's lock when we add and delete cl objects.
Every cl object should use it's own lock to protect itself.
We also add some helper functions to ease the adding and
removing operations.
