Also, it's conceivable that ext3 is implicated here, so it might be saner to perform initial investigation on ext2.
(when kjournald writes back a page via its buffers, the page remains "dirty" as far as the VFS is concerned. Later, someone tries to do a writepage() on it and we'll discover the buffers' cleanness and the page will be cleaned without any I/O being performed. All the throttling _should_ work OK in this case. But ext2 is more straightforward.) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
