From: Yan Zheng Date: Thu, 9 Oct 2008 15:46:24 +0000 (-0400) Subject: Btrfs: Remove offset field from struct btrfs_extent_ref X-Git-Tag: v2.6.29-rc1~27^2~9^2~55^2~56^2~6 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3bb1a1bc42f2ae9582c28adf620484efcd4da38d;p=pandora-kernel.git Btrfs: Remove offset field from struct btrfs_extent_ref The offset field in struct btrfs_extent_ref records the position inside file that file extent is referenced by. In the new back reference system, tree leaves holding references to file extent are recorded explicitly. We can scan these tree leaves very quickly, so the offset field is not required. This patch also makes the back reference system check the objectid when extents are in deleting. Signed-off-by: Yan Zheng --- Reading git-diff-tree failed
