See http://www.infradead.org/rpr.html The first patch ensures ->end_io is always called for direct I/O requests that pass it in, even if there was a zero length write, or if an error occured. The existing users have been updated to ignore it, but XFS will make use of it in the future, and a comment in ext4 suggests it might be useful for it as well. The other two simplify the XFS direct I/O code. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
