From 29c58472ec2af073c4f858a61236fbedfc2923ac Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 17 Nov 2016 09:48:30 -0800 Subject: net_sched: sch_fq: use hash_ptr() When I wrote sch_fq.c, hash_ptr() on 64bit arches was awful, and I chose hash_32(). Linus Torvalds and George Spelvin fixed this issue, so we can use hash_ptr() to get more entropy on 64bit arches with Terabytes of memory, and avoid the cast games.
