From 182846a00f489849c55d113954f0c4a8a286ca39 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 31 Mar 2016 10:08:14 +0200 Subject: tty: vt, remove reduntant check MAX_NR_CONSOLES and MAX_NR_USER_CONSOLES are both 63 since they were introduced in 1.1.54. And since vc_allocate does: if (currcons >= MAX_NR_CONSOLES) return -ENXIO; if (!vc_cons[currcons].d) { if (currcons >= MAX_NR_USER_CONSOLES && !capable(CAP_SYS_RESOURCE)) return -EPERM; } the second check is pointless. Remove both the check and the macro MAX_NR_USER_CONSOLES.
