This is an issue with the 4.9 tree, not mainline. The hash is
incorrect but the problem appears valid.

Compare:

2aa6d036b716 ("mm: numa: avoid waiting on freed migrated pages")

from v4.9.36 with the upstream commit from 4.12:

3c226c637b69 ("mm: numa: avoid waiting on freed migrated pages")

It is missing this diff.

The original commit conflicted due to lack of commit 82b0f8c39a38 ("mm:
join struct fault_env and vm_fault") in 4.9 so it wasn't a clean
application, must have just gotten lost in the noise.

Cheers,
Nathan
