What version is that patch against? This problem should be fixed by the
patch set from Akinobu Mita. I tested cpu hot-plugging on my system

Hi Jeff,
My patch was against (4.3.0-rc2) bcee19f424a.
I do see now that commit 1356aae08338 (blk-mq: avoid setting
hctx->tags->cpumask before allocation) has equivalent fix.
Thanks for the information.
