* Btrfs: add tests for find_lock_delalloc_rangeJosef Bacik2013-11-113-0/+359
| | | | | | | | | | | | | | So both Liu and I made huge messes of find_lock_delalloc_range trying to fix stuff, me first by fixing extent size, then him by fixing something I broke and then me again telling him to fix it a different way. So this is obviously a candidate for some testing. This patch adds a pseudo fs so we can allocate fake inodes for tests that need an inode or pages. Then it addes a bunch of tests to make sure find_lock_delalloc_range is acting the way it is supposed to. With this patch and all of our previous patches to find_lock_delalloc_range I am sure it is working as expected now.

* Btrfs: add a sanity test for btrfs_split_itemJosef Bacik2013-11-112-0/+234
| | | | | | | | | | While looking at somebodys corruption I became completely convinced that btrfs_split_item was broken, so I wrote this test to verify that it was working as it was supposed to. Thankfully it appears to be working as intended, so just add this test to make sure nobody breaks it in the future.

* Btrfs: separate out tests into their own directoryJosef Bacik2013-09-012-0/+429
The plan is to have a bunch of unit tests that run when btrfs is loaded when you build with the appropriate config option. My ultimate goal is to have a test for every non-static function we have, but at first I'm going to focus on the things that cause us the most problems. To start out with this just adds a tests/ directory and moves the existing free space cache tests into that directory and sets up all of the infrastructure.
