King <bjki...@us.ibm.com> - 2015-05-28 17:08:13 == Make sure we have the host lock held when calling scsi_report_bus_reset. Fixes a crash seen as the __devices list in the scsi host was changing as we were iterating through it. == Comment: #8 - Wen Xiong <wenxi...@us.ibm.com> - 2015-08-06 11:09:25 == Release of bug changed to Ubuntu14.04. He has tested the patch and " yes the patch worked". We have upstream the patch last month.
