From 940ea00b0646f50170c2f66957a84c0ba1737f0c Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Thu, 27 Jan 2022 00:36:26 +0000 Subject: ipv6: don't zero inet_cork_full::fl after use It doesn't appear there is any reason for ip6_cork_release() to zero cork->fl, it'll be fully filled on next initialisation. This 88 bytes memset accounts to 0.3-0.5% of total CPU cycles. It's also needed in following patches and allows to remove an extar flow copy in udp_v6_push_pending_frames().
