don't know:

 triton:~/tip> git fetch "https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git/log/?h=kspp/gcc-plugin/stackleak-v13"
 fatal: repository 'https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git/log/?h=kspp/gcc-plugin/stackleak-v13/' not found

How many patches are in there, and how clean is the series? I.e. it would be nice 
to have another submission (assuming it's a clean series with not too many 
patches).

Thanks,
