From 9b23062840e7c685ef0a0b561285d6e3a3b6811b Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Thu, 26 Jan 2012 15:01:12 -0500 Subject: Btrfs: advance window_start if we're using a bitmap If we span a long area in a bitmap we could end up taking a lot of time searching to the next free area if we're searching from the original window_start, so advance window_start in order to make sure we don't do any superficial searching.
