I got the compilation error on next-20150204:

In file included from arch/arm/probes/kprobes/core.c:37:

Thanks for reporting this, is it OK if I add to a patch to fix this a
line saying "Reported-by: Janusz UÅycki <j.uzycki@xxxxxxxxxxxxxx>"?


Whilst the extra '*' looks like an obvious typo, it's interesting that
your error message implies that it's allowed in some situations and that
the version of GCC that I use (4.9.1) doesn't complain about it.
If it's valid C, I've no idea what that syntax that might represent.

I've not find such extension in C11 but likely gcc's team knows the answer.
It also compiles using gcc 4.8.3. However I thing more people use older compilers
for different platforms.
