Hello,

I have implemented a write() call for my character driver. I need to get the page address of the "__user" buffer passed in write() call from user space. The idea is to get the actual physical address corresponding to user address and then do DMA operations using that physical address. But for that I will require page address first. Is there any way I can get the corresponding page address of a "__user" buffer??

Thanks in advance,
Vishal
