xfs: optimize log flushing in xfs_fsync If we have a pinned inode it must have a log item attached to it. Usually that log item will have ili_last_lsn already set, in which case we only need to flush the log up to that LSN instead of doing a full log force. This gives speedups of about 5% in some fsync heavy workloads. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>
