H A Dlocktypes.rst48 - local_lock
56 - local_lock
58 On non-PREEMPT_RT kernels, local_lock functions are wrappers around
158 local_lock chapter
161 local_lock provides a named scope to critical sections which are protected
164 On non-PREEMPT_RT kernels local_lock operations map to the preemption and
168 local_lock(&llock) preempt_disable()
176 The named scope of local_lock has two advantages over the regular
183 - If lockdep is enabled the local_lock gains a lockmap which allows to

161 local_lock chapter
164 I local_lock forniscono nomi agli ambiti di visibilità delle sezioni critiche
167 Sui kernel non-PREEMPT_RT le operazioni local_lock si traducono
171 local_lock(&llock) preempt_disable()
187 - Se viene abilitato lockdep, allora local_lock ottiene un lockmap che

197 I kernel PREEMPT_RT sostituiscono local_lock con uno spinlock_t per CPU, quindi
