From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Benjamin Marzinski Date: Wed, 17 Jun 2020 13:31:37 -0500 Subject: [PATCH] libmultipath: make dm_flush_maps only return 0 on success dm_flush_maps() returned both 0 and 1 on error, depending on which part of the function it was in, but the caller was always treating 0 as a success. Make dm_flush_maps() always return 1 on error and 0 on success.
