This is missing from proc(5). Original patch: https://lore.kernel.org/all/20200423200316.164518-6-gladkov.alexey@gmail.co= m/ The kernel documentation shows the option: https://www.kernel.org/doc/html/latest/filesystems/proc.html#mount-options This option is useful when mounting proc for a container nested for example= in a Docker container that hides certain parts of /proc, otherwise one is not allowed to mount /proc (https://lkml.kernel.org/lkml/cover.1597931457.git.gladkov.alexey@gmail.com= /). It might be useful to add a note about this as well. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.=
