From: David Chinner Date: Thu, 10 Apr 2008 02:22:24 +0000 (+1000) Subject: [XFS] Ensure xfs_bawrite() errors are checked. X-Git-Tag: v2.6.26-rc1~1147^2~21 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=db7a19f2c89d99b66874a7e0c0dc681ff1f37b4e;p=linux-2.6-omap-h63xx.git [XFS] Ensure xfs_bawrite() errors are checked. xfs_bawrite() can return immediate error status on async writes. Unlike xfsbdstrat() we don't ever check the error on the buffer after the call, so we currently do not catch errors at all here. Ensure we catch and propagate or warn to the syslog about up-front async write errors.
