Ever since commit91c7794713("ovl: allow filenames with comma"), the following example was legit overlayfs mount options: mount -t overlay overlay -o 'lowerdir=/tmp/a\,b/lower' /mnt The conversion to new mount api moved to using the common helper generic_parse_monolithic() and discarded the specialized ovl_next_opt() option separator. Bring back ovl_next_opt() and use vfs_parse_monolithic_sep() to fix the regression.

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.
