The set fixes a splat in devmap percpu allocation when we alloc the flush bitmap. Patch 1 is a prerequisite for the fix in patch 2, patch 1 is rather small, so if this could be routed via -net, for example, with Tejun's Ack that would be good. Patch 3 gets rid of remaining PCPU_MIN_UNIT_SIZE checks, which are percpu allocator internals and should not be used.
Thanks!
Daniel Borkmann (3): mm, percpu: add support for __GFP_NOWARN flag bpf: fix splat for illegal devmap percpu allocation bpf: do not test for PCPU_MIN_UNIT_SIZE before percpu allocations
