To modify the common prob, I need to rebuild the common driver, but the driver I am develop is not just for myself, I could ask everyone who will use this specail sd card to rebuild their driver(or kernel).
So is it possible to modify the priority of prob just calling some existing kernel APIs? On Thu, Apr 19, 2012 at 10:40 PM, Tirtha Ghosh <[email protected]> wrote: > Sorry missed ur whole details.
