EXT3 works. It is just dog slow and yes there is plenty of evidence
to EXT3s problems. Even from the author himself. Just review the kernel
threads and mailing lists. Note that a lot of the problem have been fixed.

Well that isnt exactly true. EXT3 is a bolt on to EXT2 which was always
there. Reiser is also a long time kernel at least from 2.2. XFS is also
a long time Linux supporter and its inclusion into the main tree had
nothing to do with quality.
Just because something isn't in the main tree doesn't mean that the quality
is lacking. A lot of times it is just politics.
There is a reason that all major distributions supported XFS, Reiser and JFS
before RedHat and it has nothing to do with quality.
