Vlastimil has already pointed that out. MCL_FUTURE doesn't clear

The only
remaining question I have is should we have 2 new mlockall flags so that
the caller can explicitly set VM_LOCKONFAULT in the mm-def_flags vs

We do actually have an MCL_LOCKED, we just call it MCL_CURRENT. Would
you prefer that I match the name in mlock2() (add MLOCK_CURRENT

Hi, thanks for considering
mlock() allows a user to control page out of program memory, but this
comes at the cost of faulting in the entire mapping when it is
allocated. For large mappings where the entire area is not necessary
this is not ideal. Instead of forcing all locked pages to be present
when they are allocated,
