btrfs: check if mount opts are applied
This new test will apply different mount points and check if they were applied by reading /proc/self/mounts. Almost all available btrfs options are tested here, leaving only device=, which is tested in btrfs/125 and space_cache, tested in btrfs/131. This test does not apply any workload after the fs is mounted, just checks is the option was set/unset correctly. Kernel with the following patch should pass the test: btrfs: reset compression level for lzo on remount Signed-off-by: Marcos Paulo de Souza <mpdesouza@suse.com> Reviewed-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
