From: Wang Shilong Date: Thu, 17 Jul 2014 03:44:12 +0000 (+0800) Subject: Btrfs: fix wrong max inline data size limit X-Git-Url: http://git.hungrycats.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=714d45d8ffd17e560d82d99cba76047a053fe161;p=linux Btrfs: fix wrong max inline data size limit inline data is stored from offset of @disk_bytenr in struct btrfs_file_extent_item. So substracting total size of struct btrfs_file_extent_item is wrong, fix it.
