Subject: [PATCH 5/6] [XFS] Remove unused parameter from xfs_reclaim_inodes
Date: Sun, 15 Mar 2009 22:46:42 +1100	[thread overview]
Message-ID: <1237117603-26071-6-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1237117603-26071-1-git-send-email-david@fromorbit.com>

The noblock parameter of xfs_reclaim_inodes() is only
ever set to zero. Remove it and all the conditional
code that is never executed.
