Btrfs: integrate integrity check module into btrfs
This is the last part of the patch series. It modifies the btrfs code to use the integrity check module if configured to do so with the define BTRFS_FS_CHECK_INTEGRITY. If this define is not set, the only effective change is that code is added that handles the mount option to activate the integrity check. If the mount option is set and the define BTRFS_FS_CHECK_INTEGRITY is not set, that code complains in the log and the mount fails with EINVAL. Add the mount option to activate the usage of the integrity check code. Add invocation of btrfs integrity check code init and cleanup function on mount and umount, respectively. Add hook to call btrfs integrity check code version of submit_bh/submit_bio. Signed-off-by: Stefan Behrens <sbehrens@giantdisaster.de>
