[PATCH 0/2] Fixes to flow cache for AF-specifc flowi structs

[David Ward <david.ward@ll.mit.edu>]

v2: Return the length of the flow key as a multiple of sizeof(flow_compare_t),
    to reduce the number of shift operations.

These fixes to the flow cache are needed with the conversion to AF-specific
flowi structs. They are written so as to avoid introducing AF-specific code
into net/core/flow.c.

Note that __xfrm_policy_check (in net/xfrm/xfrm_policy.c) still allocates a
struct flowi on the stack and passes it to flow_cache_lookup. My understanding
is that since this is on the stack, this will not be aligned, and therefore it
will cause problems with flow_hash_code and flow_key_compare. Is that correct?

  net: Align AF-specific flowi structs to long
  net: Handle different key sizes between address families in flow
    cache
