No, I'll pick it up for 4.9 merge. Mikulas added it for sparc or something. I cannot recall _the_ reason (I wasn't maintaining DM back then) but at the time both Alasdair and Joe Thornber reasoned that it needed to go -- and that if it was really needed that it should be done in terms of a proper patch to sched.h, etc. So I'm not sure how this dm-bufio local cond_resched() wrapper still got in... happy to take your patch. Please respond with whatever SOB you'd like applied to the patch header. Thanks, Mike -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
