I was basing my response on outdated information: https://mahmoudhatem.wordpress.com/2016/02/08/oracle-uek-4-where-is-my-io-scheduler-none-multi-queue-model-blk-mq/ (Also didn't want to risk turning on MQ on one of my machines just to word my response, especially if not having CFQ is somehow involved in this corruption bug!) -- You are receiving this mail because: You are watching the assignee of the bug.
