From 3bb1a1bc42f2ae9582c28adf620484efcd4da38d Mon Sep 17 00:00:00 2001 From: Yan Zheng Date: Thu, 9 Oct 2008 11:46:24 -0400 Subject: 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.
