From 5f56406aabdf5444d040c5955effc665b1d0dbaf Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Tue, 22 Jan 2008 16:47:59 -0500 Subject: Btrfs: Fix hole insertion corner cases There were a few places that could cause duplicate extent insertion, this adjusts the code that creates holes to avoid it. lookup_extent_map is changed to correctly return all of the extents in a range, even when there are none matching at the start of the range.
