Vivek Goyal 027065b726 ovl: Use out_err instead of out_nomem
Right now we use goto out_nomem which assumes error code is -ENOMEM.  But
there are other errors returned like -ESTALE as well.  So instead of
out_nomem, use out_err which will do ERR_PTR(err).  That way one can put
error code in err and jump to out_err.

This just code reorganization and no change of functionality.

I am about to add more code and this organization helps laying more code
and error paths on top of it.

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.
