[PATCH 1/4] xfs: always use iget in bulkstat

To: xfs@xxxxxxxxxxx
Subject: [PATCH 1/4] xfs: always use iget in bulkstat
From: Dave Chinner <david@xxxxxxxxxxxxx>
Date: Fri, 18 Jun 2010 17:32:51 +1000
Cc: security@xxxxxxxxxx
In-reply-to: <1276846374-23916-1-git-send-email-david@xxxxxxxxxxxxx>
References: <1276846374-23916-1-git-send-email-david@xxxxxxxxxxxxx>
From: Christoph Hellwig <hch@xxxxxx>

The non-coherent bulkstat versionsthat look directly at the inode
buffers causes various problems with performance optimizations that
make increased use of just logging inodes.  This patch makes bulkstat
always use iget, which should be fast enough for normal use with the
radix-tree based inode cache introduced a while ago.
