[PATCH 4.14 47/61] block/ndb: add WQ_UNBOUND to the knbd-recv workqueue

[Greg Kroah-Hartman]

From: Dan Melnic <d...@fb.com>

[ Upstream commit 2189c97cdbed630d5971ab22f05dc998774e354e ]

Add WQ_UNBOUND to the knbd-recv workqueue so we're not bound
to a single CPU that is selected at device creation time.
