Hi, > What is effect of calling local_irq_disable and local_irq_enable from > an interrupt context?
Just what the name says. It disables / enables the interrupts on the local processor. Please note that you should not enable interrupts in an atomic context (For. E.g. while holding a spinlock) - as that may lead to a deadlock. > > Does local_irq_disable disable preemption implicitly? Yes.
