Hello!
This is a series of miscellaneous patches for v7.1. 7/11 and 8/11
were generated with the assistance of an LLM named Claude. The prompt
directed Claude at existing Linux-kernel code, and I inspected the output
to verify that the expected changes were made. I also undertook the
usual testing.
The patches themselves are as follows:
1. Add a textbook-style trivial preemptible RCU.
2. kvm-check-branches.sh: Remove in favor of kvm-series.sh.
3. Make hangs more visible in torture.sh output.
4. Adjust scenarios for default lazy preemption.
5. Print informative message for test without recheck file.
6. Fix numeric "test" comparison in srcu_lockdep.sh.
7. Ditch ref_scale_shutdown in favor of torture_shutdown_init().
8. Ditch rcu_scale_shutdown in favor of torture_shutdown_init().
9. Fix SRCU read flavor macro comments.
10. Fix s/they disables/they disable/ typo in srcu_read_unlock_fast().
11. Document that RCU Tasks Trace grace periods now imply RCU grace
periods.
Thanx, Paul
