From 3954096d4b1adab6fbb3c26de37ddd4f781e072f Mon Sep 17 00:00:00 2001 From: Alexander Block Date: Wed, 1 Aug 2012 12:46:05 +0200 Subject: [PATCH] Btrfs: fix check for changed extent in is_extent_unchanged The previous check was working fine, but this check should be easier to read. Also, we could theoritically have some exotic bugs with the previous checks.
