md/raid1: intialise start_next_window for READ case to avoid hang
Neil, I've been testing these patches for the past week or two to see if
they help a raid1 "check" hang I had.
They seem to help, but I noticed the above patch is different from what
you originally sent on the list.
The original patch has an extra chunk:
@@ -1444,6 +1445,7 @@ read_again:
r1_bio->state = 0;
r1_bio->mddev = mddev;
r1_bio->sector = bio->bi_iter.bi_sector + sectors_handled;
+ start_next_window = wait_barrier(conf, bio);
goto retry_write;
}
Is the correct patch with or without this chunk?
Thanks,
Bill
