From b8a0b8e94648179b92191e5cf4fd3c4379b31cc4 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Fri, 29 Apr 2016 14:18:03 -0700 Subject: [PATCH] raid5: delete unnecessary warnning If device has R5_LOCKED set, it's legit device has R5_SkipCopy set and page != orig_page. After R5_LOCKED is clear, handle_stripe_clean_event will clear the SkipCopy flag and set page to orig_page. So the warning is unnecessary.
