Hi Now that LZ4 compression support is in 3.11-rc1, I have written the following two patches for Squashfs to use it.

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 Phillip -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
