[ Upstream commitb566d38857] Commitfb1f16d74e("usb: gadget: f_fs: change ep->status safe in ffs_epfile_io()") added a new ffs_io_data::status field to fix lifetime issues in synchronous requests. While there are no similar lifetime issues for asynchronous requests (the separate ep member in ffs_io_data avoids them) using the status field means the USB request can be freed earlier and that there is more consistency between the synchronous and asynchronous I/O paths.

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.
