Subject: [PATCH 0/2] mark some slabs as visible not mergeable

This fixes an old bug in iproute2's ss command because it was
reading slabinfo to get statistics. There isn't a better API
to do this, and one can argue that /proc is a UAPI that must
not change.

Therefore this patch set adds a flag to slab to give another
reason to prevent merging, and then uses it in network code.

The patches are against davem's linux-net tree and should also
goto stable as well.

Stephen Hemminger (2):
  slab: add flag to block merging of UAPI elements
  net: mark slab's used by ss as UAPI
