From: Philip Wernersbach To: linux-kernel@vger.kernel.org Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 609 Lines: 14 I'm trying to add some functionality to User-mode Linux that requires the UML kernel to call a custom syscall I've added to the host kernel. This should be technically possible since UML runs in the userspace, but I can't figure out how to call the syscall, as the syscall() function isn't defined in UML. Are there other ways I can accomplish this?
