Why isn't the field an unsigned int / size_t? I don't see much value
in having the size be signed...
No idea :) This code long predates me.
It's that way because the original Sun spec for the API said so.
It makes little sense to change it just to unsigned. The additional 2G
it would give doesn't really solve the tuning problem on a 64G system.
This is simply a spec that has become outdated by modern hardware.
Ah, but an unsigned integer on a 64-bit system supports that kind of
precision ;). Or are you saying you're crazy enough to run PAE mode
with that much RAM 0-o?
int and unsigned on amd64 are 32-bit types. To get a 64-bit integer, you
need (unsigned) long.
