There are significant clients of the LZO library - crypto, btrfs,
jffs2, ubifs, squashfs and zcache.  So let's give all those people a cc
and ask that they test the LZO changes once they land in linux-next.
For correctness and performance, please.

The core compression and decompression code has been thoroughly tested, so I
do not expect major problems.

Good testing after the merge and feedback about build or performance issues
(and improvements!) is highly appreciated.

The addition of the lzo tree to linux-next caused this problem for ARM
imx_v6_v7_defconfig:

In file included from /home/arnd/linux-arm/arch/arm/boot/compressed/decompress.c:40:0:
/home/arnd/linux-arm/arch/arm/boot/compressed/../../../../lib/decompress_unlzo.c:34:34: fatal error:

lzo/lzo1x_decompress.c: No such file or directory

Since the file was renamed, anything including it needs to be updated to the
new file name.

I will add that patch to my tree.

Cheers,
Markus

Sorry if I missed it (bad connectivity this week), but is someone going
to send a pull request to get this LZO update from linux-next into
Linus's tree?  The window is closing soon isn't it?
