__io_remove_buffers used for two purposes, the first is removing buffers for non ring based lists, which implies that it can be called multiple times for the same list. And the second is for destroying lists, which is not perfectly reentrable for ring based lists. It's confusing, so just have a helper for the legacy pbuf buffer removal, make sure it's not called for ring pbuf, and open code all ring pbuf destruction into io_put_bl().

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.
