some version_string() magic i'm not aware of?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  i'm puzzled by this snippet from init/version.c:

...
#define version(a) Version_ ## a
#define version_string(a) version(a)

int version_string(LINUX_VERSION_CODE);
...

puzzled because this appears to be the only place in the entire tree
that uses the macro version_string().  so is there some reason it even
exists, as opposed to just using version() as it's defined there?
