folio_has_private() is an attractive nuisance; filesystem authors generally don't realise that it actually checks two flags (one of which is never set by bcachefs). There's no need to check the private flag at all; for folios owned by bcachefs, we know that folio->private is NULL when the private flag is clear and non-NULL when the private flag is set.

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 reStructuredText 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.
