From 8e9b9362266dd16255473c080d846b13e27247bf Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Sun, 6 Dec 2009 12:24:31 +0100 Subject: Doc/stable rules: add new cherry-pick logic - it is possible to submit patches for the stable queue without sending them directly stable@kernel.org. If the tag (Cc: stable@kernel.org) is available in the sign-off area than hpa's script will filter them into the stable mailbox once it hits Linus' tree. - Patches which require others to be applied first can be also specified.

However, the create and remove file interfaces were failing to propagate the const promise which the only functions they call offer.
