Hello,

a small remark on the non-code parts:

This seems contradictionary information.

However, I welcome more compression options in kernel and filesystem
land, so I'm very interested in this patch.
Recently, on the filesystem side there seems to be some effort to
modularize the decompressors, instead of the use of #ifdef's.

The other architectures (especially used in embedded) need to hook in
on this, getting rid of the many out-of-tree patches for kernel/fs
decompression.
