This is a janitorish patch to 1) remove private TRUE/FALSE #def's in
favor of using the standard enum from linux/stddef.h and 2) switch the
variables holding those values to type 'bool' (from linux/types.h)
since it both seems more appropriate and allows for potentially better
optimization.
As a truly minor aside, I removed a couple of comments documenting
a 'do_safe' parameter that seems to no longer exist.

This seems a bit strange, using a boolean as an integer (yes I know, it
works but semantically...). What about:
