From a273208edd55463b3bcd8b77a6fe8ba54afc6940 Mon Sep 17 00:00:00 2001 From: Yan Date: Tue, 6 Nov 2007 10:26:28 -0500 Subject: [PATCH] Fix EXTENT_MAP_INLINE off by one in btrfs_drop_extents Don't set hint_byte to EXTENT_MAP_INLINE when 'end == extent_end' or 'start == key.offset' . The inline extent will be truncated in these cases.
