JIRA: https://issues.redhat.com/browse/RHEL-33888
Status: Linus
Conflicts: For consistency drop btrfs hunks because it isn't supported in
CentOS Stream and other backports also drop such hunks.
The cifs source has been moved in CentOS Stream so manually
apply rejected hunks to fs/smb/client/cifsfs.h and
fs/smb/client/inode.c.
Dropped hunks for ntfs3 because the source is not present in the
CentOS Stream source tree.
Upstream commit cc14d24026704 ("hpfs: Convert symlinks to
read_folio") is not present which causes fuzz 1 for hunk #1.
CentOS Stream commit 892da692fa ("shmem: support idmapped
mounts for tmpfs") is present, so a patch reorder was needed
with appropriate adjustments.

fs: port ->rename() to pass mnt_idmap
Convert to struct mnt_idmap.
Last cycle we merged the necessary infrastructure in
256c8aed2b42 ("fs: introduce dedicated idmap type for mounts").
This is just the conversion to struct mnt_idmap.
Currently we still pass around the plain namespace that was attached to a
mount. This is in general pretty convenient but it makes it easy to
conflate namespaces that are relevant on the filesystem with namespaces
that are relevent on the mount level. Especially for non-vfs developers
without detailed knowledge in this area this can be a potential source for
bugs.
Once the conversion to struct mnt_idmap is done all helpers down to the
really low-level helpers will take a struct mnt_idmap argument instead of
two namespace arguments. This way it becomes impossible to conflate the two
eliminating the possibility of any bugs. All of the vfs and all filesystems
only operate on struct mnt_idmap.
