Subject: [PATCH 2/2] Ext3: return ENOMEM rather than EIO if sb_getblk fails
Date: Thu, 13 Jan 2011 18:47:14 +0800 [thread overview]
Message-ID: <1294915634-3413-1-git-send-email-wangshilong1991@gmail.com> (raw)
From: Wang Shilong <wangsl-fnst@cn.fujitsu.com>
It will be better to have ENOMEM return rather than EIO,because
the only reason that sb_getblk fails is allocation fails.
