Fine, then here's a patch:

Meanwhile, reiser4 seems to be working fine and is nice and fast.

I did a "time bk -r co" for the current 2.6 tree, and here
are the results for reiser4 and ext3 on 2.6.0-test4:

Reiser4:
real    1m55.077s
user    0m30.740s
sys     0m36.558s

Ext3:
real    3m48.438s
user    0m26.400s
sys     0m13.205s
