[PATCH] Add security_file_permission() to AIO paths.
Currently, there are no LSM hooks in the AIO codepaths, which means that LSM based access controls are not revalidated upon AIO read and write operations. The patch below adds the security_file_permission() LSM hook prior to the VFS aio_read()/aio_write() calls.
