Frankly I am not sure, but after reading Documentation/gpio.txt - where it says: Accessing such GPIOs requires a context which may sleep, for example a threaded IRQ handler, and those accessors must be used instead of spinlock-safe accessors without the cansleep() name suffix. we can immediately deduced that threaded IRQ handler is sleepable/blocking-allowed, and therefore process context.
