get_user_pages question
 

Hi frenz ,

I came across get_user_pages() function . I found that this function is used when the there is no need of kernel buffering (buffer cache ) so the data from the device is directly placed in the userspace . But still i dont know when and how to use this function . Do anyone have some code snippets which tells me how the transfer is happening or any theory that tells how it happen which would be quite useful .. Thanks in advance

Can you post the code of the function here?
