[PATCH] SELinux: extend task_kill hook to handle signals sent by AIO completion
This patch extends the security_task_kill hook to handle signals sent by AIO completion. In this case, the secid of the task responsible for the signal needs to be obtained and saved earlier, so a security_task_getsecid() hook is added, and then this saved value is passed subsequently to the extended task_kill hook for use in checking.
