 Thanks.

 Unrelated question. Comparing the drivers/md/raid5.c file in the Linus's 
2.6.23-rc6 tree and in your md-for-linus one I'd found the following 
difference in the expand-related part of the handle_stripe5() function:

-		s.locked += handle_write_operations5(sh, 1, 1);
+		s.locked += handle_write_operations5(sh, 0, 1);

 That is, in your case we are passing rcw=0, whereas in the Linus's case the 
handle_write_operation5() is called with rcw=1. What code is correct ?

 Regards, Yuri
