I am pleased to announce the release of a new lzip patch for linux-4.9.22.
This patch adds lzip decompression support to the linux kernel.
The homepage of lzip is at http://www.nongnu.org/lzip/lzip.html
The patch can be downloaded from
http://download.savannah.gnu.org/releases/lzip/kernel/
Instructions on how to apply the patch can be found at

Linux already offers a lot of compression formats. Then, why lzip?
Because lzip is the only gzip-like LZMA compressor featuring a
well-designed format:
* Lzma-alone is a toy format lacking integrity checking or even a
proper header.
* Xz has a complex and not properly designed format[1]. It can
compress the kernel image a little more than lzip on some
architectures (about 4% on x86) by using a different binary filter
for each architecture. But this increase in complexity does not
improve the decompression time (much less the boot time) compared
with lzip.
Also the xz compressor is the only one needing special options to
compress data for linux, and xz decompression is the only one that
may fail because of wrong options used at compression time.

If you are distributing software in xz format, please consider using
lzip instead. See http://www.nongnu.org/lzip/xz_inadequate.html and
