Description

We don't have the mlockall/munlockall syscalls as documented in [1]. We have at
least one tool in base that would benefit from it: cryptsetup. Hopefully someone
more familiar with the VM system can implement it without much effort as we
already have mlock/munlock.

Cheers,
Alex Hornung

We do have mlockall(2) but only MCL_FUTURE is currently supported. MCL_CURRENT still needs work to be done.
