Ian Kent 956e3ad810 fs: port ->mknod() to pass mnt_idmap 
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/dir.c.
	Dropped hunks for ntfs3 because the source is not present in the
	CentOS Stream source tree.
	CentOS Stream commit 892da692fa ("shmem: support idmapped
	mounts for tmpfs") is present, which cuases hunks #2-#4 to be
	rejected, manually apply the hunks.
	CentOS Stream commit f0f830cd7e ("ceph: create symlinks with
	encrypted and base64-encoded targets") is present and resulted
	in fuzz against fs/ceph/dir.c hunk #2.
	Upstream commit 863f144f12add ("vfs: open inside ->tmpfile()")
	is missing causing fuzz against fs/ext2/namei.c.
	Upstream commit 7d37539037c2f ("fuse: implement ->tmpfile()")
	is missing causing fuzz in hunk #4 against fs/fuse/dir.c.
	CentOS Stream commit 892da692fa ("shmem: support idmapped
	mounts for tmpfs") is present, so a patch reorder was needed
	with appropriate adjustments.

    fs: port ->mknod() 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.
