Has this been fixed in 2.6? If so, it would improve the speed of mail servers that use maildir, (I think mbox should be ok, since the data that was appended has a good chance of still being in memory. Though, to compute UIDL for pop3, it has to read the entire mbox file, forcing other mbox users out of cache, and then evening up performance between the two. Though this patch should help maildir more.) - 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/
