Ick ick ick, why not just put the C "namespace" on all uapi files if you are including them from c++ code? I'm sure this isn't the only problem that has this problem, right?
This is valid C, no need to start worrying about C++ reserved names.
We've done this before and it's a simple enough change in order to be friendly toward others.
That being said, it's been like this for two years so presumably anyone who is using this header from C++ is already `extern "C" { ...}' around their #include.
I'm OK with the patch as-is, but if we run into this issue more often, we might want to look at doing something kernel-wide.
I'm not sure what though. Adding
#ifdef __cplusplus extern "C" { #endif
...
#ifdef __cplusplus } #endif
into every uapi file might work. Unpleasing.
