[RFC PATCH 0/4] rcu: Expedited GP polling improvements

From: Frederic Weisbecker
Date: Wed Mar 16 2022 - 10:43:06 EST


I initially wanted to shape that into the form of reviews or questions
but I thought I might as well send patches.

Be careful, it's fairly possible I misunderstood some things and those
patches are completely off the track.

At least TREE07 looks happy.

Thanks,
