Subject: Map memory to user, then map it back to kernel
Date: Wed, 09 Aug 2006 10:17:07 +0300	[thread overview]
Message-ID: <44D98BF3.5060706@scalemp.com> (raw)

Hi folks.

I am looking for a way to map a memory (allocated with get_free_pages()) 
from kernel space to user space, so that I will later be able to map it 
back with get_user_pages().

I tried remap_pfn_range(), but it didn't work as it assumes the memory 
being mapped is IO range (marking vma with VM_IO flag), while 
get_user_pages() works on regular memory.

Any ideas?

Thanks.
Alexander Sandler.
