Conrad Meyer 3a37091931 ioat(4): Fix race between process_events and reset_hw ... In the case where a hardware error is detected during ioat_process_events, hardware may advance (by one descriptor, probably) and a subsequent ioat_process_events may race the intended ioat_reset_hw followup. In that case, the second process_events would observe a completion update that does not match the software "last_seen" status, and attempt to successfully complete already-failed descriptors. Guard against this race with the resetting_cleanup flag. Reviewed by: bdrewery, markj Sponsored by: Dell EMC Isilon		2016-11-11 20:09:54 +00:00
