Hi all.
With the addition of the VM_MERGEABLE flag to vm_flags post-2.6.31, the last bit in vm_flags has been used.
I have some code in TuxOnIce that needs a bit too (explicitly mark the VMA as needing to be atomically copied, for GEM objects), and am not sure what the canonical way to proceed is. Should a new unsigned long be added? The difficulty I see with that is that my flag was used in shmem_file_setup's flags parameter (drm_gem_object_alloc), so that function would need an extra parameter too..
Regards,
Nigel
