From 275c51c4e34ed776d40a99dd97c1deee50303b07 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Thu, 8 Aug 2013 09:20:32 +1000 Subject: md: fix safe_mode buglet. Whe we set the safe_mode_timeout to a smaller value we trigger a timeout immediately - otherwise the small value might not be honoured. However if the previous timeout was 0 meaning "no timeout", we didn't. This would mean that no timeout happens until the next write completes, which could be a long time.
