grumble/
ive often wanted lsmod -b  to tell me that list.  or something like that.
maybe a different rc

[jimc at samwise wk-next]$ grep -P \\bparams /proc/dynamic_debug/control
kernel/params.c:177 [params]parse_args =_ "doing %s, parsing ARGS: '%s'\012"
kernel/params.c:156 [params]parse_one =_ "Unknown argument '%s'\012"
kernel/params.c:152 [params]parse_one =_ "doing %s: %s='%s'\012"
kernel/params.c:139 [params]parse_one =_ "handling %s with %p\012"
[jimc at samwise wk-next]$ modprobe params
modprobe: FATAL: Module params not found in directory
/lib/modules/5.15.0-rc2-sept
[jimc at samwise wk-next]$ echo $?
1

I guess it comes down to whats in /proc/

[jimc at samwise wk-next]$ wc /proc/modules
133 798 7818 /proc/modules
[jimc at samwise wk-next]$ lsmod | wc
    134     471    6170

or is it (lsmod user prog) already scouring /sys/module (via lib Id presume)?
it seems that
/sys/modules/* minus col-1-of  /proc/modules
would tell builtins

just musing out loud...
