list what is using a module

[matt zagrabelny <z@saturnsys.com>]

hello,

i would like to remove a module. when i do "rmmod <module_name>" i get:

<module_name>: device or resource busy

is there a way to list processes that are using a module?

are processes the only thing that need to be stopped before a module can
be removed?

please advise.

thanks,
matt zagrabelny
