From ad47047220777460c6d7dc8333808591f29e5c17 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Tue, 28 Feb 2017 11:55:16 -0500 Subject: [PATCH] dm raid: fix raid "check" regression due to improper cleanup in raid_message() While cleaning up awkward branching in raid_message() a raid set "check" regression was introduced because "check" needs both MD_RECOVERY_SYNC and MD_RECOVERY_REQUESTED flags set. Fix this regression by explicitly setting both flags for the "check" case (like is also done for the "repair" case, but redundant set_bit()s are perfectly fine because it adds clarity to what is needed in response to both messages -- in addition this isn't fast path code).
