SubjectRCU: Question on force_qs_rnp
Hello Paul

I have some questions for you .
in force_qs_rnp func , if "f(rdp)" func return true we will call rcu_report_qs_rnp func
report a quiescent state for this rnp node, and clear grpmask form rnp->qsmask.
after that , can we make a check for this rnp->qsmask, if rnp->qsmask == 0,
we will check blocked readers in this rnp node, instead of jumping directly to the next node .
