Do you mean that there weren't any problems to begin with, or that the
patch looked OK?

I am pretty sure there were some problems.  There were several instances
where pool_put() was called just _after_ code went to elevated spl to
protect element removal from a datastructure, then reduced spl again.  If
it was necessary to go to splsoftnet() to protect a list operation, etc.
it seems pretty clear that the adjacent pool operation also needed to be
protected...
