From 1ed850f356a0a422013846b5291acff08815008b Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 11 Oct 2012 13:50:13 +1100 Subject: [PATCH] md/raid5: make sure to_read and to_write never go negative. to_read and to_write are part of the result of analysing a stripe before handling it. Their use is to avoid some loops and tests if the values are known to be zero. Thus it is not a problem if they are a little bit larger than they should be. So decrementing them in handle_failed_stripe serves little value, and due to races it could cause some loops to be skipped incorrectly. So remove those decrements.
