From 9d66e233c7042da27ec699453770f41e567a0442 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 25 Aug 2010 16:54:15 -0400 Subject: [PATCH] Btrfs: load free space cache if it exists This patch actually loads the free space cache if it exists. The only thing that really changes here is that we need to cache the block group if we're going to remove an extent from it. Previously we did not do this since the caching kthread would pick it up. With the on disk cache we don't have this luxury so we need to make sure we read the on disk cache in first, and then remove the extent, that way when the extent is unpinned the free space is added to the block group. This has been tested with all sorts of things. Signed-off-by: Josef Bacik --- Reading git-format-patch failed
