I realized I didn't update fscrypt_mergeable_bio() to take metadata
encryption into account, so bios will be more fragmented than required.
I'll fix it in v3.

Sure, I'll do that! I sent out v2 of this patch series earlier today,
so would you want me to send out a rebased version asap? or when
I send out v3?
Also, newbie question - multi-partition support is the same as
multi-device support, right?

Limitations:
Metadata encryption with sparse storage has not been implemented yet in
this patch.
This patch requires the metadata encryption key to be readable from
userspace, and does not ensure that it is zeroed before the program exits
for any reason.

mkfs.f2fs takes both these arguments, and stores the encryption algorithm
in the superblock of the FS.
The rest of the programs only take '-M', and use the encryption algorithm
stored in the superblock of the FS.
