From 77ca6cdf0ab8a42f481ec997911bc89e79138723 Mon Sep 17 00:00:00 2001 From: Lukas Czerner Date: Wed, 27 Oct 2010 21:30:11 -0400 Subject: [PATCH] ext4: Use return value from sb_issue_discard() Use return value from sb_issue_discard() as return value in ext4_issue_discard(). Since sb_issue_discard() may result in more serious errors than just -EOPNOTSUPP it is worth to inform user of this function about them to handle error cases properly.
