uvm replaced the ma= chvm in netbsd.=C2=A0

For a time, Chuck set it up = to run in parallel with the existing VM. You could start a process and pick= which vm it used. For a while, it defaulted to the existing one. Then, at = some point, it defaulted to uvm. Then, at some point, the old one was remov= ed.

more here:


via search terms=C2=A0
uvm replaces machvm netbsd

chuck was a long time contributor to netbsd IIRC, but= last time we talked, he was using Linux.

These days I know he's hacki= ng on FreeBSD's storage stack with me at work :). I think he's stil= l a netbsd contributor. I see his name in the commit log often..=C2=A0
