Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1317 Lines: 52 Hello Nick, what's the reason behind disallowing get_user_pages() on VM_RESERVED regions? vmmon uses VM_RESERVED on its 'vma' as otherwise some kernels used by SUSE complained loudly about mismatch between PageReserved() and VM_RESERVED flags. I'll remove it from vmmon for >= 2.6.14 kernels as that bogus test never made to Linux kernel, but I cannot find any reason why get_user_pages() should not work on VM_RESERVED (or VM_IO for that matter) user pages. Can you show me reasoning behind that decision ?
