Marco Elver f03ad37824 kfence: skip __GFP_THISNODE allocations on NUMA systems ... [ Upstream commit e64f81946a ] On NUMA systems, __GFP_THISNODE indicates that an allocation _must_ be on a particular node, and failure to allocate on the desired node will result in a failed allocation. Skip __GFP_THISNODE allocations if we are running on a NUMA system, since KFENCE can't guarantee which node its pool pages are allocated on.
