commitd47748e5aeupstream. Current behavior is to automatically disable metacopy if redirect_dir is not enabled and proceed with the mount. If "metacopy=on" mount option was given, then this behavior can confuse the user: no mount failure, yet metacopy is disabled. This patch makes metacopy=on imply redirect_dir=on. The converse is also true: turning off full redirect with redirect_dir= {off|follow|nofollow} will disable metacopy. If both metacopy=on and redirect_dir={off|follow|nofollow} is specified, then mount will fail, since there's no way to correctly resolve the conflict.

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.
