RCU pull request for v7.2
This pool request contains two branches:
rcutorture.2026.05.24: Torture test updates. Improve kvm-series.sh
script by adding examples in its header comment. Lazy RCU is more
fully tested now by replacing call_rcu_hurry() with call_rcu() and
doing rcu_barrier() to motivate lazy callbacks during a stutter
pause. Add more synonyms for the "--do-normal" group of torture.sh
command-line arguments
misc.2026.05.24: Miscellaneous changes. Reduce stack usage of
nocb_gp_wait() to address frame size warning when built with
CONFIG_UBSAN_ALIGNMENT. The synchronize_rcu() call can detect
the flood and latches a normal/default path temporary switching
to wait_rcu_gp() path. Document using rcu_access_pointer() to
fetch the old pointer for lockless cmpxchg() updates. Simplify
some RCU code using clamp_val(). Fix a kerneldoc header comment
typo in srcu_down_read_fast().
