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
