Date: Mon, 27 Sep 2010 16:09:57 +0200 From: Lukas Czerner <lczerner@...hat.com> To: linux-ext4@...r.kernel.org Cc: tytso@....edu, rwheeler@...hat.com, sandeen@...hat.com, adilger@...ger.ca, lczerner@...hat.com Subject: [PATCH 1/4] 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.
