SubjectRe: [PATCH v1] blk-mq: free hctx->ctxs in queue's release handler
From
Hi Jens,

Could you consider this patch for v4.1?

http://marc.info/?l=linux-kernel&m=143342792910832&w=2

The issue is one obvious use-after-free and can be reproduced easily
via 'sudo modprobe loop;sleep 1;sudo rmmod loop' on linus tree:

Thanks,
Ming Lei
