From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Benjamin Marzinski Date: Tue, 9 Aug 2022 16:46:27 -0500 Subject: [PATCH] libmultipath: return success if we raced to remove a map and lost _dm_flush_map() was returning failure if it failed to remove a map, even if that was because the map had already been removed. Return success in this case.
