Dan Williams aa75db0080 ioat: close potential BUG_ON race in the descriptor cleanup path ... Since ioat_cleanup_preamble() and the update of the last completed descriptor are not synchronized there is a chance that two cleanup threads can see descriptors to clean. If the first cleans up all pending descriptors then the second will trigger the BUG_ON. Signed-off-by: Dan Williams <dan.j.williams@intel.com>		2010-03-03 21:21:10 -07:00
