I am guessing that test is ok, but we are doing the test each time that
we change the function. We always end calling that kind of functions in
several places. Shouldn't be good to rename the function to
__postcopy_ram_supported_by_host()
and do a toplevel function that is:
bool postcopy_ram_supported_by_host(void)
{
static bool first_time = true;
static supported = false;
if (firt_time) {
first_time = false;
supported = __postcopy_ram_supported_by_host()
}
return supported;
}
Notice that I don't know how slow the mmap + usefault thing is, but I
guess that the values would not change while running, no?
It has a review-by because I don't see anything wrong with it.
