just a short question:
is -EAGAIN here really intentional? wouldn't -ENOMEM be better?
mm/mmap.c ~780 do_mmap_pgoff()
/* mlock MCL_FUTURE? */
if (vm_flags & VM_LOCKED) {
unsigned long locked = mm->locked_vm << PAGE_SHIFT;
locked += len;
if (locked > current->rlim[RLIMIT_MEMLOCK].rlim_cur)
return -EAGAIN;
}
TIA,
Herbert

Standards require this one:
[EAGAIN]
[ML] The mapping could not be locked in memory, if required by
mlockall(), due to a lack of resources.
