SDIO irq handler context

SDIO irq handler context

[Kalpesh Rathod]

Hi,

SDIO driver irq handler runs in which context?
It always runs in process context ?
or
It runs in either interrupt context or process context? If this is the case,
in_interrupt can be used to distinguish?

Regards,
Kalpesh

It's run in process context as the sdio accessors sleep.
