LZ4 is a lightweight compression algorithm which can be used on embedded systems to reduce CPU and memory overhead (in comparison to the standard zlib compression). These patches add the wrapper code to allow Squashfs to use the existing LZ4 decompression code, and the necessary configuration option. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAABAgAGBQJUjgIJAAoJEJAch/D1fbHUArwP/iDiDSpqxdfTQHwUKxB57skO 0iBzg6bXPlqwmsnllegg0SV0vOvFjpWiXWpOOtAVCJlfbov8DgUndsigpvG3UhD/ qJpNXAJ+xSdOzBqj3bS7SOu2DwPY8Gz4rxGQcNN3PsuOVR/EUgAnNlv22ZHY10A5 XQVyPbkwZ73TrZ2uKA8leWArFtCbM4oYGpxP+ramEox8nVFEOtixn5IcX5WkbGEL Yt0NRw8K8vDIIETWVariugUFE4C1olFk+YmqqAw7cmDGJ70cEg5jh9ocNkwDIZPj I9BNtkggBRMaCPwGsH6IvahMFUyWLQUgGayfY/fgbRiB9ZuYIQ1lyPDhzbgWczoE o34eXAIDdmfPrmYlDEBDkYnXXtwuYqdOVYOtcEnyFEYqpHfaeS2h2s9nTiM+rz21 v0UEaDRmPtlkK/ZdLKUsrOf+8y9ejkT0R67swFaguHshL6EHey7X5ghmOuwCoL9x fzGWtPFR+Nbqga5T3dwf+apvyUVrPaw6gZu36NNim2779ZgpnIPzW6MEYUMhtXCn ef2+NvS9AeGyo7kiqlNQrihQWZSN0W/AiVsEeulzk5h+adzSNQ5eipzAO9DAAp16 8muY4nq51bOGVaWzqJz/KacCmt7i0qUdmS1p4l2uqPp9gH/s/S91yrYn/iszf3AV CpwU2i9g3nQu9ecDc1Os =mr7J -----END PGP SIGNATURE----- Merge tag 'squashfs-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/pkl/squashfs-next Pull squashfs update from Phillip Lougher: "These patches optionally add LZ4 compression support to Squashfs.
