[SRU][F:linux-bluefield][PATCH] UBUNTU: SAUCE: xfrm: IPsec Export xfrm_policy_lookup_bytype function

[Tim Gardner]

I'm not sure what to think about this. Philosophically it is no 
different then the patch set from a couple weeks ago that enforced 
EXPORT_SYMBOL_GPL and broke some out of tree drivers. Have you checked 
with the maintainers to get their opinion ? I can just about guess what 
they'll say.
