Doing nearly 100% of the writepage from the flusher threads would also be preferable from the filesystem point of view - getting I/O from one thread helps to make it more local and work around all the stupid I/O controller logic that tries to make our life difficult. Of course getting rid of ->writepage from the AOPs API one day would also be nice to simplify the filesystems code, but it's not that important. -- 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
