From 254a2d14fa77ac8a1b64f6171ec5f717f0753b53 Mon Sep 17 00:00:00 2001 From: Liu Bo Date: Wed, 17 Sep 2014 21:36:41 +0800 Subject: [PATCH] Btrfs: fix wrong parse of extent map's tracepoint The tracepoint of extent map doesn't parse @flag correctly, we set @flag via set_bit(), so we need to parse it on a bit bias. Also add the missing flag, EXTENT_FLAG_FS_MAPPING.
