Hi reviewers,

I suggest to backport a commit to Linux 4.4 and 4.9 stable tree.
Reason: the double decrease of nr_reserved_highatomic will generate
many high atomic pages in the system and it may cause out-of-memory
issues under long duration test.

commit:4855e4a7f29d6d10b0b9c84e189c770c9a94e91e
subject:mm: prevent double decrease of nr_reserved_highatomic
kernel version to apply to:kernel 4.4 and 4.9

thanks,
Miles
