4.9-stable review patch. If anyone has any objections, please let me know.

No objections but if you are grabbing that one please check if you have it's follow on fix.

c0ee554906c3 ("pid: Handle failure to allocate the first pid in a pid namespace")

There were a few cases not handled but the fix below, that made a more comprehensive fix desirable.

Ok, but it looks like that commit needs to also go into 4.14.y as well, as the original patch here, 8896c23d2ef8 ("pidns: disable pid allocation if pid_ns_prepare_proc() is failed in alloc_pid()") showed up in 4.12.

Is that ok?

thanks,
