[PATCH v2 00/13] Core RCU patches for 6.4

From: Joel Fernandes (Google)
Date: Sat Mar 25 2023 - 13:34:06 EST


Hello,

These are core RCU patches for 6.4. I am resending as there are few more
patches for MAINTAINERS file changes, and few more tags. Plus I dropped the
Frederick's patch that Thomas took in for fixing the entry code.

o MAINTAINERS files additions and changes.

o Fix hotplug warning in nohz code.

o Tick dependency changes by Zqiang.

o Lazy-RCU shrinker fixes by Zqiang.

o rcu-tasks stall reporting improvements by Neeraj.

o Other changes.

Let me know if any objections to anything.

thanks,

- Joel
