And, in Red Hat 7.1 (not EL) days, it was a supported journaled filesystem. Before EXT3 was supported.
EXT3, once became supported, had the advantage that many of the tools that supported EXT2 could work better with it.

Sheesh. The guy goes to jail and today nobody even remembers what he was all about.
reiserfs is not EXT2, not XFS, not flash-fs, not ZFS, not AFS, not ...
It was much better than all of them in exactly 1 way - it was built
to efficiently handle large number of small files.
With reiserfs:
a) a "hello world!" file does not occupy 4k of disk space (tail packing)
b) "rm -rf /" takes 1 second (try to delete some files from ZFS, lucky ot be done by tomorrow).
c) "ls -ltR /" does not take 10 days
It was very good while it lasted.
Of course today everybody wants checksums, and dedup, and built-in raid,
and snapshots, and ... and so reiserfs joins the Dodo bird, the steam-powered airplane,
and the home made icecream as fond memory of last year's trees were taller,
grass was greener.
