[ Upstream commitb2dd05f107] Let helper ovl_i_path_real() return the realinode to prepare for checking non-null realinode in RCU walking path. [msz] Use d_inode_rcu() since we are depending on the consitency between dentry and inode being non-NULL in an RCU setting. There are some changes from upstream commit: 1. Context conflicts caused by73db6a063c("ovl: port to vfs{g,u}id_t and associated helpers") is handled.

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.
