It doesn't bother me :) I just think its the technical better
and also most likely code-wise cleaner solution to this problem.
Cancellation wouldn't be necessary since an unnecessary
netif_schedule() doesn't really matter.

Hmm... Do you mean during destroying... It's probably not very long,
but deleting and creating qdiscs especially for some virtual devices
can take longer I guess.

I was referring to your statement "but also some overhead when
cancelling this workqueue" and assumed you meant during packet
processing. In the destruction path it really doesn't matter at
all.
