Hi,
I wanted to verify/clarify if using schedule_timeout after acquiring a spinlock is safe?. So basically you have a situation where you are working on a critical code and you acquire a spin lock and you end up using a schedule_timeout after say setting the current task to Interruptible state 'cause you are waiting for some user space code to fill in some buffer from which you want to read.
So my doubt is simple, is it safe to acquire a spinlock and use schedule_timeout.
I assume the task is put in the run queue and will "ALWAYS" be scheduled back after the specified delay in schedule_timeout.
