I agree with the above, hence:

Acked-by: Danilo Krummrich <dakr at redhat.com>

However, the documentation below seems to be more about a common DRM_VM_BIND IOCTL?
I guess your commit refers to the end where it talks about common VM_BIND helpers.

Otherwise the patch is moving the "DRM_VM_BIND" paragraph somewhere below the
"Dev_coredump"paragraph. Is there some kind of "Done-Section" I'm missing?
