Vivek Goyal 60124877b9 ovl: Do not set dentry type ORIGIN for broken hardlinks
If a dentry has copy up origin, we set flag OVL_PATH_ORIGIN.  So far this
decision was easy that we had to check only for oe->numlower and if it is
non-zero, we knew there is copy up origin.  (For non-dir we installed
origin dentry in lowerstack[0]).

But we don't create ORGIN xattr for broken hardlinks (index=off).  And with
metacopy feature it is possible that we will install lowerstack[0] but
ORIGIN xattr is not there.  It is data dentry of upper metacopy dentry
which has been found using regular name based lookup or using REDIRECT.  So
with addition of this new case, just presence of oe->numlower is not
sufficient to guarantee that ORIGIN xattr is present.

So to differentiate between two cases, look at OVL_CONST_INO flag.  If this
flag is set and upperdentry is there, that means it can be marked as type
ORIGIN.  OVL_CONST_INO is not set if lower hardlink is broken or will be
broken over copy up.

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
