From 6126e3caf7468a07cc1a8239d9e95090acedd3ca Mon Sep 17 00:00:00 2001 From: Filipe David Borba Manana Date: Tue, 19 Nov 2013 16:19:24 +0000 Subject: Btrfs: fix ordered extent check in btrfs_punch_hole If the ordered extent's last byte was 1 less than our region's start byte, we would unnecessarily wait for the completion of that ordered extent, because it doesn't intersect our target range.
