This can easily double the time for compiling a driver but does not provide any benefit for the compile tester, so it's better left disabled. In addition, any 'inline' function that is not also 'static' and that contains an 'if' causes a warning like include/linux/string.h:212:2: note: in expansion of macro 'if' if (strscpy(p, q, p_size < q_size ? p_size : q_size) < 0) ^~ include/linux/compiler.h:162:4: warning: '______f' is static but declared in inline function 'strcpy' which is not static without this patch, and I could not come up with a nice fix for that. In combination with my patch to always enable 'CONFIG_COMPILE_TEST' during 'randconfig' builds, we can at least hide these warnings for most users.
