Re: Question regarding User Space and the Kernel

Hi..

3. It is not swapped out to disk.
  
After 2nd thought and checking 
http://lxr.linux.no/source/arch/i386/lib/usercopy.c#L849, I see no 
function related to making sure the related page(s) aren't swapped out. 
So, I think it's OK if it hits swapped out pages since AFAIK code paths 
that use copy_{to,from}_user are free to sleep.

regards,

Mulyadi
