For what it's worth, ReiserFS was only merged into the 2.4.1-pre8 kernel yesterday. (see: http://linuxtoday.com/news_story.php3?ltsn=2001-01-18-004-04-NW-KN) It never was in the 2.4.0 source. This may not help your supermount patching though. Just passing on some info; my kernel patching experience is limited to smooth sailing ... no troubleshooting. Dave.
