commit 182846a00f489849c55d113954f0c4a8a286ca39 upstream.
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.
