From db7a19f2c89d99b66874a7e0c0dc681ff1f37b4e Mon Sep 17 00:00:00 2001 From: David Chinner Date: Thu, 10 Apr 2008 12:22:24 +1000 Subject: [PATCH] [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.
