Subject[PATCH net 0/3] Fix for BPF devmap percpu allocation splat
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.


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
