From e6c58299502fb94e329b7a35a12feacde6c1cbc6 Mon Sep 17 00:00:00 2001 From: "Emilio G. Cota" Date: Mon, 10 Sep 2018 13:40:07 -0400 Subject: qht: constify qht_lookup seqlock_read_begin takes a const param since c04649eeea ("seqlock: constify seqlock_read_begin", 2018-08-23), so we can constify the entire lookup.
