From 74255aa07d292385ca3a4a4e8f0bc492d9bdd116 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 15 Mar 2013 09:47:08 -0400 Subject: Btrfs: add some free space cache tests We keep hitting bugs in the tree log replay because btrfs_remove_free_space doesn't account for some corner case. So add a bunch of tests to try and fully test btrfs_remove_free_space since the only time it is called is during tree log replay. These tests all finish successfully, so as we find more of these bugs we need to add to these tests to make sure we don't regress in fixing things. I've hidden the tests behind a Kconfig option, but they take no time to run so all btrfs developers should have this turned on all the time.
