Hello everyone,

Beau pointed me towards a performance bug in reiserfs, where reiserfs_write_super would be called excessively.  

Turns out that 2.4.9 included some new super handling code that 
interacted poorly with how reiserfs uses kupdated calls to 
write_super to trigger writebacks of metadata.

This is most obvious with benchmarks like bonnie++, where 
2.4.9 and 2.4.10 reiserfs do very poorly.

This patch makes things much better in my tests, I'd appreciate 
a few more testers.  The only risk is reiserfs using slightly 
more memory, but only if I've screwed something up.

-chris
