[PATCH] fs: ext4: Add metadata checksums support

[Fredrik Hallenberg]

Thanks for trying it out. I have only used it on a custom arm-based
board. I have done quite a lot of writing with and without metadata
flag and have also tried to trigger errors that require journal
recovery. It has worked well but of course it is hard to be sure that
the code will handle every case.
