Subject: [PATCH 0/2] Squashfs: add LZ4 compression
Date: Mon, 22 Jul 2013 03:21:01 +0100 [thread overview]
Message-ID: <1374459663-15363-1-git-send-email-phillip@squashfs.org.uk> (raw)
Hi
Now that LZ4 compression support is in 3.11-rc1, I have written the
following two patches for Squashfs to use it.

Squashfs: add LZ4 compression support
Squashfs: Add LZ4 compression configuration option

These patches are also available in the git tree here:
browse: https://git.kernel.org/cgit/linux/kernel/git/pkl/squashfs-lz4.git
git clone: git://git.kernel.org/pub/scm/linux/kernel/git/pkl/squashfs-lz4.git
LZ4 support has (obviously) also been added to the squashfs-tools
(Mksquashfs and Unsquashfs). This is available from the Squashfs-tools
git repository here:
browse: https://git.kernel.org/cgit/fs/squashfs/squashfs-tools.git
git clone: git://git.kernel.org/pub/scm/fs/squashfs/squashfs-tools.git
When building the squashfs-tools edit the Makefile to enable LZ4
support (by default it is disabled).
LZ4 compression can be specified by using the -comp option, e.g.
% mksquashfs xxx img.sqsh -comp lz4
The use of LZ4 high compression can be specified using -Xhc, e.g.
% mksquashfs xxx img.sqsh -comp lz4 -Xhc
