Subject: [PATCH] xfs: wait for direct I/O to complete in fsync and write_inode
Date: Sat, 6 Mar 2010 08:20:18 -0500 [thread overview]
Message-ID: <20100306132018.GA31360@infradead.org> (raw)
We need to wait for all pending direct I/O requests before taking care of
metadata in fsync and write_inode.
Note that the write_inode hunk will causes conflicts when merging with
mainline, I'm not sure how to best deal with that.
