While going thro’ run time power management code in K39
power/runtime.c file, am seeing a function definition as given below. Any idea,
what “__releases” & “__acquires” are doing in this function definition?
static int rpm_callback(int (*cb)(struct device *), struct
device *dev)
__releases(&dev->power.lock)
__acquires(&dev->power.lock)
{
int
retval;
….
return
retval;
}
