From 7209049d40dc37791ce0f3738965296f30e26044 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Tue, 31 Jul 2018 17:27:02 -0400 Subject: dm kcopyd: return void from dm_kcopyd_copy() dm_kcopyd_copy() only ever returns 0 so there is no need for callers to account for possible failure. Same goes for dm_kcopyd_zero().
