From c4a16820d90199409c9bf01c4f794e1e9e8d8fd8 Mon Sep 17 00:00:00 2001 From: Christian Brauner Date: Tue, 28 Jan 2025 11:33:41 +0100 Subject: fs: add open_tree_attr() Add open_tree_attr() which allow to atomically create a detached mount tree and set mount options on it. If OPEN_TREE_CLONE is used this will allow the creation of a detached mount with a new set of mount options without it ever being exposed to userspace without that set of mount options applied.
