The lower stacks of all the ovl inode aliases should be identical and there is redundant information in ovl_entry and ovl_inode. Move lowerstack into ovl_inode and keep only the OVL_E_FLAGS per overlay dentry. Following patches will deduplicate redundant ovl_inode fields. Note that for pure upper and negative dentries, OVL_E(dentry) may be NULL now, so it is imporatnt to use the ovl_numlower() accessor.

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.
