[PATCH 0/8] Assorted rhashtable fixes and cleanups

From: NeilBrown
Date: Thu May 03 2018 - 23:54:46 EST


This series contains some bugfixes, mostly minor though one
is worthy of a stable backport I think - tagged with Fixes and Cc: stable.

Then there are improvements to walking, which have been discussed
to some degree already.
Finally a code simplification which I think is correct...

Thanks,
NeilBrown
