[PATCH 0/3] Make rcutorture safe(r) for arm64

From: Paul E. McKenney
Date: Thu May 08 2025 - 19:42:30 EST


Hello!

This series makes a few small updates to make rcutorture run better
on arm64 servers. Remaining issues include TREE07 .config issues
that are addressed by Mark Rutland's porting of PREEMPT_LAZY to arm64
and by upcoming work to handle the fact that arm64 kernels cannot be
built with CONFIG_SMP=n. In the meantime, the CONFIG_SMP=n issue can
be worked around by explictly specifying the TREE01, TREE02, TREE03,
TREE04, TREE05, TREE07, SRCU-L, SRCU-N, SRCU-P, TASKS01, TASKS03, RUDE01,
TRACE01, and TRACE02 scenarios, preferably in a script. (But if you
want typing practice, don't let me stand in your way!)

1. Check for "Call trace:" as well as "Call Trace:".

2. Reduce TREE01 CPU overcommit.

3. Remove MAXSMP and CPUMASK_OFFSTACK from TREE01.

Thanx, Paul
