[PATCH BUGFIX RFC 0/2] reverting two commits causing freezes
From: Paolo Valente
Date: Fri Jan 18 2019 - 06:52:37 EST
Hi Jens,
a user reported a warning, followed by freezes, in case he increases
nr_requests to more than 64 [1]. After reproducing the issues, I
reverted the commit f0635b8a416e ("bfq: calculate shallow depths at
init time"), plus the related commit bd7d4ef6a4c9 ("bfq-iosched:
remove unused variable"). The problem went away.
Maybe the assumption in commit f0635b8a416e ("bfq: calculate shallow
depths at init time") does not hold true?
Thanks,
Paolo
