Subject: [PATCH 0/6 v3] ext4: Check journal inode extents more carefully


This series changes ext4 to properly check extent tree blocks of journal inode.
Omitting these (which is a limitation of block validity checks) leads to crash
in ext4_cache_extents() in case the extent tree of the journal inode is
suitably corrupted. 

Changes since v1:
* Added Reviewed-by tags from Lukas
* Fixed two more unrelated minor bugs in block validity testing spotted by

Changes since v2:
* Add more Reviewed-by tags from Lukas
* Fix intermediate compilation failure in patch 3/6
