I'd ask you to include my "lzo-update" branch in linux-next: git://github.com/markus-oberhumer/linux.git lzo-update > The changelog for patch 2/3 says: > > : This commit updates the kernel LZO code to the current upsteam version > : which features a significant speed improvement - benchmarking the Calgary > : and Silesia test corpora typically shows a doubled performance in > : both compression and decompression on modern i386/x86_64/powerpc machines. > > There are significant clients of the LZO library - crypto, btrfs, > jffs2, ubifs, squashfs and zcache.
