The initial patch cleared this for all requests, which is wrong since internal uses can't have this cleared as that's what they are using to pass data. The fix moved the initialization to the mq_ops->initialize_rq_fn(), but that's only a partial fix since it only catches uses from blk_get_request(), not requests coming from the file system. Keep the non-fs initialization, and add the IDE entry clear IFF RQF_DONTPREP isn't set and it's a passthrough request.

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.
