+Subject: [PATCH] listmount04.c: Update struct mnt_id_req support for kernel >= 6.18
+
+Kernel change from v6.18-rc7
+78f0e33cd6c93 ("fs/namespace: correctly handle errors returned by grab_requested_mnt_ns")
+causes the test failure with following error message:
+listmount04.c:128: TFAIL: invalid mnt_id_req.spare expected EINVAL: EBADF (9)
+
+The fix require following changes:
+
+* struct mnt_id_req got new member mnt_ns_fd in v6.18-rc7. That is
+fixed in a fallback defintion in lapi/. If the fallback is used is now
+done via typedef (that requires also update in statmount.h).
+
+* New kernels (>= 6.18) have also different errno. This is fixed by
+runtime check.
