Just noticed this bit of FUD. Last time I did some static analysis on
stack usage, reiserfs alone would blow away 3k, while xfs was somewhere
below. Reiserfs was improved afaik, but I'd still expect it to be worse
than xfs until shown otherwise.
Maybe reiserfs simply isn't used that much in nfs+*fs+md+whatnot+scsi
setups?
