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. 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" * tag 'squashfs-updates' of git://git.kernel.org/pub/scm/linux/kernel/git/pkl/squashfs-next: Squashfs: Add LZ4 compression configuration option Squashfs: add LZ4 compression support
