Please ask Stephen to include the tree in linux-next, for a 3.7 merge. 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. So let's give all those people a cc and ask that they test the LZO changes once they land in linux-next. For correctness and performance, please.
