so in kcmdline we would have modulename.param instead of modulename.param=1?
I guess we need to update kmod then, because currently we ignore and
treat this case as a wrong token. From a quick look, allowing it in
kmod would be as simple as removing a condition check.

Note, both will still work. And it didn't change much. Today, anything
that uses "module_param()" with bool type (a quick git grep shows 570
users), already do not require a value.
Randomly looking at one... drivers/input/mouse/synaptics_i2c.c, you can
insmod synaptics_i2c.ko no_filter
no need to add a "=1" to that.
But anything else will still require a value. I just want to allow
other parameters that act like a boolean to not require one.

true... but currently "modprobe synaptics_i2c" doesn't get the
parameter correctly from kernel command line if it doesn't have a
value. And I agree this not something that changed but rather a bug in
kmod waiting to be fixed.

And it's fixed now with a proper test added.

thanks
