Eric Dumazet 9bef83edfb fib_hash: embed initial hash table in fn_zone ... While looking for false sharing problems, I noticed sizeof(struct fn_zone) was small (28 bytes) and possibly sharing a cache line with an often written kernel structure. Most of the time, fn_zone uses its initial hash table of 16 slots. We can avoid the false sharing problem by embedding this initial hash table in fn_zone itself, so that sizeof(fn_zone) > L1_CACHE_BYTES We did a similar optimization in commit a6501e080c (Reduce memory needs and speedup lookups) Add a fz_revorder field to speedup fn_hash() a bit.
