[PATCH v2 0/1] Add 16K Support for f2fs

[Daniel Rosenberg <drosen@google.com>]

F2fs filesystems currently have two large restrictions around block size.
The block size must equal the page size, and the block size must be 4096.

The following patch, along with the associated f2fs-tools patch set, relax the
latter restriction, allowing you to use 16K block size f2fs on a 16K page size
system. It does not allow mounting 4K block size f2fs on a 16k page system.

Doing that would require a lot more work, requiring a refactor of all block
sized struct similar to the userspace patches, as well as handling the block
reading/writing at sub page boundaries. I'm currently leaving that to future
work.

changes for v2:
Adjusted format string
