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. Regards, -- Leon
