Given we now have iio_device_claim_direct_scoped() to perform automatic releasing of direct mode at exit from the scope that follows it, this can be used in conjunction with guard(mutex) etc remove a lot of special case handling. Note that in this particular example code, there is no real reason you can't read channels via sysfs at the same time as filling the software buffer. To make it look more like a real driver constrain raw and processed channel reads from occurring whilst the buffer is in use.

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.
