From 0181e58f91c1edbf835edb7a87d6dfe81374709d Mon Sep 17 00:00:00 2001 From: Yan Date: Wed, 30 Jan 2008 14:39:54 -0500 Subject: btrfs_drop_extent fixe for inline items > 8K When truncating a inline extent, btrfs_drop_extents doesn't properly handle the case "key.offset > inline_limit". This bug can only happen when max line size is larger than 8K.
