When it comes to exposes the system call, we prefer to use size_t for
buffer sizes (even if the kernel uses int or unsigned int), purely for
documentation purposes.

I suggest using "ssize_t or size_t" to keep the text parallel with "int orunsigned int". We shouldn't insist on size_t for buffer sizes when the naturalinterpretation of the value is signed (as in the return value for 'read' etc.)or is too large for malloc etc.
