Summary

We could allocate a bit flag for it if we implement it one day. For now, make it a no-op flag.

This is part of the update of DRM drivers to Linux 6.12.81.

Fixes: rG8f95998393f42f368fe22abd9a25c7fa4304e02a (use real hash from src.git)

We do have more *node* alloc functions in slab.h; are we really sure we do not need it there anywhere?

You are right, I didn’t look at how to implement that before.

I prepared D56590 to replace this patch.

You probably want to abandon this review then?

Yes
