Pardon the intrusion, but I thought you might be interested to know that as a humble user I noticed actual user-visible breakage from 59ec715 "ucounts: Fix rlimit max values check": https://bugzilla.kernel.org/show_bug.cgi?id=215596 I'm not sure I understand everything that's going on in this thread but it does seem very relevant. You guys might want to double-check the behavior in the particular scenario described there. I'm mostly sending this to make sure everything is cross-linked.
