Subject: [GIT PULL] locking changes for v6.10

Linus,

Please pull the latest locking/core Git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git locking-core-2024-05-13

# HEAD: 532453e7aa78f3962fb4d86caf40ff81ebf62160 locking/pvqspinlock/x86: Use _Q_LOCKED_VAL in PV_UNLOCK_ASM macro

Locking changes for v6.10:

- Over a dozen code generation micro-optimizations for the atomic
and spinlock code.

- Add more __ro_after_init attributes

- Robustify the lockdevent_*() macros

Thanks,

Ingo
