[PATCH 08/39] configfs, securityfs: kill_litter_super() not needed
From: Al Viro <viro@zeniv.linux.org.uk>
Date: 2025-09-20 07:48:03
Also in:
linux-efi, linux-fsdevel, linux-mm, linux-usb, ocfs2-devel
Subsystem:
configfs, filesystems (vfs and infrastructure), security subsystem, the rest · Maintainers:
Andreas Hindborg, Alexander Viro, Christian Brauner, Paul Moore, James Morris, "Serge E. Hallyn", Linus Torvalds
These are guaranteed to be empty by the time they are shut down; both are single-instance and there is an internal mount maintained for as long as there is any contents. Both have that internal mount pinned by every object in root. In other words, kill_litter_super() boils down to kill_anon_super() for those.
