From 85c0c3eb9a6657887e3f7c5140e38f529c815ee0 Mon Sep 17 00:00:00 2001 From: Seth Forshee Date: Tue, 26 Oct 2021 13:37:21 -0500 Subject: net: sch: simplify condtion for selecting mini_Qdisc_pair buffer The only valid values for a miniq pointer are NULL or a pointer to miniq1 or miniq2, so testing for miniq_old != &miniq1 is functionally equivalent to testing that it is NULL or equal to &miniq2.
