From: Lukas Czerner Date: Thu, 28 Oct 2010 01:30:11 +0000 (-0400) Subject: ext4: Use return value from sb_issue_discard() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=77ca6cdf0ab8a42f481ec997911bc89e79138723;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git 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.
