Merge tag 'fs.move_mount.move_mount_set_group.v5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux
Pull move_mount updates from Christian Brauner:
"This contains an extension to the move_mount() syscall making it
possible to add a single private mount into an existing propagation
tree.
The use-case comes from the criu folks which have been struggling with
restoring complex mount trees for a long time. Variations of this work
have been discussed at Plumbers before, e.g.
https://www.linuxplumbersconf.org/event/7/contributions/640/
The extension to move_mount() enables criu to restore any set of mount
namespaces, mount trees and sharing group trees without introducing
yet more complexity into mount propagation itself.
The changes required to criu to make use of this and restore complex
propagation trees are available at
https://github.com/Snorch/criu/commits/mount-v2-poc
A cleaned-up version of this will go up for merging into the main criu
repo after this lands"
