From 2e7614c0736de93c8796bb2d58debb8871a59db8 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Mon, 25 Feb 2019 20:08:27 +0100 Subject: [PATCH] x86/uaccess: Remove unused __addr_ok() macro This was caught while staring at the whole {set,get}_fs() machinery. It's last user, the 32-bit version of strnlen_user() went away with 5723aa993d83 ("x86: use the new generic strnlen_user() function") so drop it. No functional changes.
