Can you help me look at this failure.

fs_bind_move09.sh、fs_bind_rbind21.sh、fs_bind_rbind35.sh、fs_bind_rbind36.sh、fs_bind_rbind39.sh、fs_bind_cloneNS06.sh are are similar errors

Hello, is there any progress in the analysis of this issue?

The failure looks like the kernel failed to propagate changes to rbind mount, no idea why you have to debug the failure yourself to figure that out.

@metan-ucw Can this error be ignored? Can we not pay attention to it? Can we not test this kind of case?
