  Kernel Traffic #15 For 22 Apr 1999
Stephen C. Tweedie said, "This is very bad: something is seriously corrupt somewhere for these put_dirty_page messages to occur." Elsewhere he added, "those are supposed to be a this-can't-happen condition." Meanwhile, David Ford and others confirmed the problem on several Linux versions.
Alan Cox pointed out that Stephen C. Tweedie was working on journalling for ext3 (which would altogether eliminate the need for fsck after unexpected reboots), and that dtfs (basically ext2 with logging) was available for 2.0 kernels.
Stephen replied that linux-privs@mit.edu was the mailing list discussing capabilities, and the last set of patches from Andrew Morgan were available at ftp://ftp.guardian.no/pub/free/linux/capabilities (this link seems dead by KT press time, however).

 2002 Linux Symposium: keynote
Stephen Tweedie Red Hat is one of our Keynote Speakers for 2002.
Stephen has been a Linux kernel hacker since early 1993, when he started helping with ext2 development, and he has worked on various parts of the kernel since, especially on filesystems and the VM.
Outside the kernel, the number of applications available for Linux has been rising steadily each year and is currently taking off in a number of markets, and Linux has given vigour to projects such as Gnome and KDE which have transformed the way Linux looks to the average user.

 Re: ext2 fragmentation (was: A fairly simple question)
Moreover, Stephen Tweedie (the author of defrag and edefrag) has rewritten the ext 2 fs allocation routines and they should produce even less fragmentation than before in the next version.
Now, thanks to Stephen's good work, the ext 2 fs tries (and succeeds in most cases) to allocate contigous blocks for the same file.

 Kernel Traffic #18 For 13 May 1999
Stephen C. Tweedie replied, "It would spoil the kernel: the kernel works very hard to make sure that even when you have different filesystem types present, the pipe and socket code is all handled by common code, not by the particular filesystem involved.
In fact, according to mmap semantics, we can't: there is no permanent memory reserved for /proc at all." Simon Richter complained that this broke libc file accesses, and Alan Cox said that relying on mmap() being available was broken (though he acknowledged it was the kernel's fault for treating 0 length mmap()s as succeeding).
Brad replied that the situation effectively prevented all but kernel hackers from tuning Linux or even performing good benchmarks; but Alan didn't think it was that big a deal, and pointed to Stephen's patches again.

While Stephen did not necessarily expect attendees to be familiar with Unix systems programming, the more you knew about Unix the easier it was to understand the presentation.

Don't count ext2 out yet though, some time later Stephen Tweedie is also going to ship a meta-data only logging file system.
The Reiserfs camp is also going to ship something they call reverse opportunistic wandering logs, employ page table remapping instead of memory copies, and add quite a witches brew of other future performance tweaks.

Interestingly, when performing a full kernel build on the same box, the d_lookup() cost is so low that it is hardly even on the map.
