This patch series is based on the RFC patch from Frederic [1]. Instead
of offering RCU_NOCB as a separate option, it is now lumped into a
root-only cpuset.cpus.isolation_full flag that will enable all the
additional CPU isolation capabilities available for isolated partitions
if set. RCU_NOCB is just the first one to this party. Additional dynamic
CPU isolation capabilities will be added in the future.
IIUC this is similar to what I suggested back in the day and you didn't
consider it [1]. Do I read this right that you've changed your mind?
I didn't said that we were not going to do this at the time. It's just
that more evaluation will need to be done before we are going to do
this. I was also looking to see if there were use cases where such
capabilities were needed. Now I am aware that such use cases do exist
and we should start looking into it.
(It's fine if you did, I'm only asking to follow the heading of cpuset
controller.)
OK, the title of the cover-letter may be too specific. I will make it
more general in the next version.
