# 52e0874f	12-Aug-2024	Sebastian Andrzej Siewior <[email protected]>	locking/rt: Add sparse annotation PREEMPT_RT's sleeping locks. The sleeping locks on PREEMPT_RT (rt_spin_lock() and friends) lack sparse annotation. Therefore a missing spin_unlock() won't be spotte locking/rt: Add sparse annotation PREEMPT_RT's sleeping locks. The sleeping locks on PREEMPT_RT (rt_spin_lock() and friends) lack sparse annotation. Therefore a missing spin_unlock() won't be spotted by sparse in a PREEMPT_RT build while it is noticed on a !PREEMPT_RT build. Add the __acquires/__releases macros to the lock/ unlock functions. The trylock functions already use the __cond_lock() wrapper.

# 4a57d6bb	22-Jan-2022	Minchan Kim <[email protected]>	locking/rwlocks: introduce write_lock_nested In preparation for converting bit_spin_lock to rwlock in zsmalloc so that multiple writers of zspages can run at the same time but those zspages are supp locking/rwlocks: introduce write_lock_nested In preparation for converting bit_spin_lock to rwlock in zsmalloc so that multiple writers of zspages can run at the same time but those zspages are supposed to be different zspage instance. Thus, it's not deadlock. This patch adds write_lock_nested to support the case for LOCKDEP.

# 8282947f	15-Aug-2021	Thomas Gleixner <[email protected]>	locking/rwlock: Provide RT variant Similar to rw_semaphores, on RT the rwlock substitution is not writer fair, because it's not feasible to have a writer inherit its priority to multiple readers. Re locking/rwlock: Provide RT variant Similar to rw_semaphores, on RT the rwlock substitution is not writer fair, because it's not feasible to have a writer inherit its priority to multiple readers. Readers blocked on a writer follow the normal rules of priority inheritance. Like RT spinlocks, RT rwlocks are state preserving across the slow lock operations (contended case).
