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

=======================
Squashfs is a compressed read-only filesystem for Linux.
-It uses zlib/lzo/xz compression to compress files, inodes and directories.
-Inodes in the system are very small and all blocks are packed to minimise
-data overhead. Block sizes greater than 4K are supported up to a maximum
-of 1Mbytes (default block size 128K).

Squashfs is intended for general read-only filesystem use, for archival
use (i.e. in cases where a .tar.gz file may be used), and in constrained
