Newer kernels (since ~v6.18-rc1) return ENOTTY instead of EINVAL when invoking ioctl(pidfd, PIDFD_GET_INFO_SHORT, info_invalid). Update the test to accept both EINVAL and ENOTTY as valid errors to ensure compatibility across different kernel versions.

I dared to add a commit which caused the change (found by Cyril Hrubis): 3c17001b21b9f ("pidfs: validate extensible ioctls")

and merged!

Thanks for fix and review!

Kind regards, Petr
