Subject: [PATCH] block/ndb: add WQ_UNBOUND to the knbd-recv workqueue
Git-commit: 2189c97cdbed630d5971ab22f05dc998774e354e
Patch-mainline: v4.18-rc1
References: bsc#1104967,FATE#325924
Add WQ_UNBOUND to the knbd-recv workqueue so we're not bound
to a single CPU that is selected at device creation time.
