* Btrfs: add a flags field to btrfs_fs_infoJosef Bacik2016-09-261-1/+1
| | | | | | | | | | | We have a lot of random ints in btrfs_fs_info that can be put into flags. This is mostly equivalent with the exception of how we deal with quota going on or off, now instead we set a flag when we are turning it on or off and deal with that appropriately, rather than just having a pending state that the current quota_enabled gets set to.

* Btrfs: self-tests: Support non-4k page sizeFeifei Xu2016-06-021-40/+45
| | | | | | | | | | | self-tests code assumes 4k as the sectorsize and nodesize. This commit fix hardcoded 4K. Enables the self-tests code to be executed on non-4k page sized systems (e.g. ppc64).

* Btrfs: add free space tree sanity testsOmar Sandoval2015-12-171-14/+6Star
| | | | | | | | | This tests the operations on the free space tree trying to excercise all of the main cases for both formats. Between this and xfstests, the free space tree should have pretty good coverage. Signed-off-by: Omar Sandoval <osandov@fb.com> Signed-off-by: Chris Mason <clm@fb.com>

* btrfs: sink parameter len to alloc_extent_bufferDavid Sterba2014-12-121-1/+1
| | | | | | | Because we're using globally known nodesize. Do the same for the sanity test function variant. Signed-off-by: David Sterba <dsterba@suse.cz>
* btrfs: unify extent buffer allocation apiDavid Sterba2014-12-121-11/+10Star
| | | | | | | | | | | Make the extent buffer allocation interface consistent. Cloned eb will set a valid fs_info. For dummy eb, we can drop the length parameter and set it from fs_info. The built-in sanity checks may pass a NULL fs_info that's queried for nodesize, but we know it's 4096. Signed-off-by: David Sterba <dsterba@suse.cz>
* Btrfs: fix qgroups sanity test crash or hangFilipe Manana2014-06-131-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Often when running the qgroups sanity test, a crash or a hang happened. This is because the extent buffer the test uses for the root node doesn't have an header level explicitly set, making it have a random level value. This is a problem when it's not zero for the btrfs_search_slot() calls the test ends up doing, resulting in crashes or hangs such as the following: [ 6454.127192] Btrfs loaded, debug=on, assert=on, integrity-checker=on (...)

* Btrfs: add sanity tests for new qgroup accounting codeJosef Bacik2014-06-101-0/+468
This exercises the various parts of the new qgroup accounting code. We do some basic stuff and do some things with the shared refs to make sure all that code works. I had to add a bunch of infrastructure because I needed to be able to insert items into a fake tree without having to do all the hard work myself, hopefully this will be usefull in the future.
