Hello, Sachin, and it looks like you hit something that Zqiang and I
have been tracking down.  I am guessing that you were using modprobe
and rmmod to make this happen, and that this happened at rmmod time.

Yes, the LTP test script rcu_torture.sh relies on modprobe to load/unload
the rcutorture module.

Whatever the reproducer, does the following patch help?

Thank you for the patch. Yes, with this patch applied, the test completes
successfully without the reported warning.

Very good, thank you!  May we have your Tested-by?

Tested-by: Sachin Sant <redacted>

Thank you, and I will apply on the next rebase.

							Thanx, Paul
