Zlib compression is used in many places in the kernel, cramfs, jffs2, squashfs, zisofs, cloop, ppp, maybe more. There used to be several copies of the code in the kernel tree, I still have a not-so-old compiled kernel with *three* copies of the zlib code in it. It's centralized now under lib/, which is a good thing (TM). When configuring the kernel, chances are you don't have to touch it. Anything else should be reported and get fixed. :) J?rn -- Fancy algorithms are slow when n is small, and n is usually small. Fancy algorithms have big constants. Until you know that n is frequently going to be big, don't get fancy. -- Rob Pike - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
