[LU-14074] LNet: lustre_rmmod fails after lnetctl is used

• Type: Bug
• Resolution: Fixed

Description

After using the lnetctl utility a reference count is taken on the lnet modules and lnetctl lnet unconfigure needs to be called in order for lustre_rmmod to remove the lnet module.

I think it would be a good idea to modify lustre_rmmod to unconfigure lnet to avoid having to do it manually.

Steps to reproduce:

modprobe lustre
lnetctl lnet configure
lustre_rmmod
