The following changes since commit 5200f5f493f79f14bbdc349e402a40dfb32f23c8: Linux 7.1-rc4 (2026-05-17 13:59:58 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/rcu/linux.git tags/rcu.release.v7.2 for you to fetch changes up to e853c1b28580ea93fda3cd729e440a3fc16fa647: Merge branches 'rcutorture.2026.05.24' and 'misc.2026.05.24' into rcu-merge.2026.05.24 (2026-06-02 19:45:08 +0200) ---------------------------------------------------------------- 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(). ---------------------------------------------------------------- Arnd Bergmann (1): rcu/nocb: reduce stack usage in nocb_gp_wait() Paul E.
