Merge branch 'dst_cache-fix-possible-races'
Eric Dumazet says:
====================
dst_cache: fix possible races
This series is inspired by various undisclosed syzbot
reports hinting at corruptions in dst_cache structures.
It seems at least four users of dst_cache are racy against
BH reentrancy.
Last patch is adding a DEBUG_NET check to catch future misuses.
