From f4245bd4ebf903541ba758ad06c118626d8c6f18 Mon Sep 17 00:00:00 2001 From: Lukas Czerner Date: Tue, 2 Nov 2010 14:07:17 -0400 Subject: ext4: fix lazyinit hang after removing request When the request has been removed from the list and no other request has been issued, we will end up with next wakeup scheduled to MAX_JIFFY_OFFSET which is bad. So check for that.
