Merge tag 'fs.idmapped.fixes.v6.0-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping

Pull idmapping fixes from Christian Brauner:

 - Since Seth joined as co-maintainer for idmapped mounts we decided to
   use a shared git tree. Konstantin suggested we use vfs/idmapping.git
   on kernel.org under the vfs/ namespace. So this updates the tree in
   the maintainers file.

 - Ensure that POSIX ACLs checking, getting, and setting works correctly
   for filesystems mountable with a filesystem idmapping that want to
   support idmapped mounts.

   Since no filesystems mountable with an fs_idmapping do yet support
   idmapped mounts there is no problem. But this could change in the
   future, so add a check to refuse to create idmapped mounts when the
   mounter is not privileged over the mount's idmapping.

 - Check that caller is privileged over the idmapping that will be
   attached to a mount.

   Currently no FS_USERNS_MOUNT filesystems support idmapped mounts,
   thus this is not a problem as only CAP_SYS_ADMIN in init_user_ns is
   allowed to set up idmapped mounts. But this could change in the
   future, so add a check to refuse to create idmapped mounts when the
   mounter is not privileged over the mount's idmapping.

 - Fix POSIX ACLs for ntfs3. While looking at our current POSIX ACL
   handling in the context of some overlayfs work I went through a range
   of other filesystems checking how they handle them currently and
   encountered a few bugs in ntfs3.

   I've sent this some time ago and the fixes haven't been picked up
   even though the pull request for other ntfs3 fixes got sent after.
   This should really be fixed as right now POSIX ACLs are broken in
   certain circumstances for ntfs3.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
