unting right.
However, there does not appear to be any special protection against a
page in a highatomic pageblock getting merged with a buddy of another
pageblock type. The pageblock would still have the right setting but on
allocation, the p

It also has been tested by Ying Huang and found to have fixed a page

It may be necessary to make this more generic for migration-related

is instructive in itself. I have no strong feelings
about this though. I see little harm in making the check but in light of
this conversation add a short comment explaining that the check should
be redundant.

bonus you can drop the WARN_ON check in the caller and make this void as
the WARN_ON check in the caller becomes redundant.

I have two minor comments but it is not critical they be addressed. If you
