Hi,
I was trying to set a module parameter for vt.c, I set it in command
line as "global_cursor_default=0". After that, I debug the kernel by
printing and check the /sys/modules/vt/parameters/global_cursor_default,
all found the parameter did not take effect. The corresponding static
variable is still keep its default value of -1.
What's wrong with my operations?
Thanks in advance.

Module parameters have to be specified as modulename.parametername=foo.
Try this instead: vt.global_cursor_default=0

I also found the reason, exactly as you said. Thanks a lot!
