Alexey Gladkov 0889f44e28 ipc: Check permissions for checkpoint_restart sysctls at open time ... As Eric Biederman pointed out, it is possible not to use a custom proc_handler and check permissions for every write, but to use a .permission handler. That will allow the checkpoint_restart sysctls to perform all of their permission checks at open time, and not need any other special code.
