Subject: [RFC PATCH v3 0/4] ipc: Store mq and ipc sysctls in the ipc namespace

This patchset changes the implementation of mq and ipc sysctls. It moves the
sysctls inside the ipc namespace.This will allow us to manage these sysctls
inside the user namespace. The implementation also removes helpers duplication
between mq and ipc sysctls.
