Subjectmlockall() with MCL_FUTURE
From
Date
Hi,
I was just going through its implementation. If mlockall() is invoked
with MCL_FUTURE, does it mean that all the existing locked mappings of
process should get unlocked ? Attaching code segment from do_mlockall().
I am using 2.4.18 kernel

static int do_mlockall(int flags)
{
...
newflags = vma->vm_flags | VM_LOCKED;
if (!(flags & MCL_CURRENT))
newflags &= ~VM_LOCKED;
error = mlock_fixup(vma, vma->vm_start, vma->vm_end,
newflags);
...
}

please cc me.

thanks
Amol
