Thanks a lot for noticing this! Yes, it's an oversight and examining the code I can see that it's an actual user-visible regression: max_inotify_instances controls time namespaces limit. I've just sent a patch to fix the issue, Cc'ing @stable: https://lore.kernel.org/linux-api/20200406171342.128733-1-dima@xxxxxxxxxx/ Thanks again, Dmitry
