There are cases where you can end up with bad data csums because of
misbehaving applications. This happens when an application modifies a
buffer in-flight when doing an O_DIRECT write. In order to recover the
file we need a way to turn off data checksums so you can copy the file
off, and then you can delete the file and restore it properly later.
