Well, after things were basically working, we started fixing all the real bugs reported by an updated checkpatch.pl
Any lines that obviously should have been longer than 80 chars were joined back to their proper length, and curly braces were moved to their proper locations. Tabs were all changed to 3 spaces each, we couldn't quite decide on 2 vs 4.
After that was done, we forward ported devfs. Proper disc management code in Linux was long overdue.
