[RFC PATCH 0/2] mm: Dont allocate pages on a offline node

From: Nico Pache
Date: Sun Dec 05 2021 - 22:34:27 EST


Prevent page allocations from occuring on an offlined node by adding a
check in _alloc_pages_node and correcting the use of for_each_node when
allocating shrinkers.

The first patch is more of a defensive check while the second patch
directly relates to an issue we have found during testing.
