The simple and obvious fix is to change "__u64" in cow_sys.h and cow.h
to be "unsigned long long",
Are you compiling a 64-bit kernel? With which GCC release?
In that case I can guess what's going on: __u64 is being defined as "unsigned
long", which is valid, and gcc is not recognizing it's the same thing as
unsigned long (and it's right since normally they're different).
However, I've never seen that (possibly I tested only before doing some
changes about this, which are in -bb1).
but this makes me think that I am missing something like an include file
with a definition somewhere.
Any ideas?
