I am afraid this is not possible. As rmmod can only get the idea whether the module is used or not from refcnt (/sys/module/nfsd/refcnt), which is set by kernel, I don't see any option how to get the information what is actually using the module. CC'ing Josh Boyer for his opinion. I agree with Václav. The only things rmmod/modprobe have to look at are the refcnt and the module dependency list (holders). If a module has its refcnt incremented by something other than another module, there is no simple way for rmmod/modprobe -r to determine that. So closing as CANTFIX. |
