From 5a17d9ed9ad702af800f184b13817e056618ba03 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Mon, 3 Apr 2017 00:51:50 +0300 Subject: flowcache: make flow_key_size() return "unsigned int" Flow keys aren't 4GB+ numbers so 64-bit arithmetic is excessive. Space savings (I'm not sure what CSWTCH is): add/remove: 0/0 grow/shrink: 0/2 up/down: 0/-48 (-48) function old new delta flow_cache_lookup 1163 1159 -4 CSWTCH 75997 75953 -44 Signed-off-by: Alexey Dobriyan Signed-off-by: David S.
