In the current code we added the correct include and we added the kernel headers path to the CFLAGS. Fixes: ce290a19609d ("selftests: add devpts selftests") Signed-off-by: Anders Roxell --- Hi, I've been running devpts_pts on a mainline kernel (4.16+git0+60cc43fc88) and the verify_invalid_ptmx_bind_mount() test failes with this failure: root@intel-core2-32:~# ./devpts_pts Failed to perform TIOCGPTPEER ioctl However, I'm still confused why I'm not able to get the test to pass. Strace showes that -ENOENT return in the TIOCGPTPEER implementation in the kernel. I think the -ENOENT gets returned from this path devpts_mntget()->devpts_ptmx_path->path_pts().
