Re: [RFC PATCH v2 0/4] Add support for LZ4-compressed kernel
I agree that the new LZO version provided shows better decompression
speed than 3.7 based. It is much improved especially for UA.
Compiler: Linaro ARM gcc 4.6.2
2. ARMv7, 1.7GHz based board

Re: [RFC PATCH v2 1/4] decompressor: Add LZ4 decompressor module
It's based on r88.
Yes, Good point.
It's about indent errors. The } is a pair of braces regarding
"while (1) {". However it compiled. It will be fixed.
Yes, right. It looks better if it's

How could it be questionable that it's worth updating the LZO code?

Re: [RFC PATCH v2 0/4] Add support for LZ4-compressed kernel
OK. If LZO is now faster than LZ4 while still compressing more then I
have no argument.

Re: [RFC PATCH v2 1/4] decompressor: Add LZ4 decompressor module
What SVN version did you use?
For safety reasons I suggest to add a temporary variable to avoid double
evaluation of isize.
Does this compile? The } is an extra one, and does not match the
original

Re: [RFC PATCH 0/4] Add support for LZ4-compressed kernels
My feeling is that in this case it is unneccessarily hard
for an outside contributor to get a patch accepted, all
because get_maintainer.pl doesn't put someone in charge.
Apparently it doesn't work
