Resetting the write index of the notification buffer on urb unlink (e.g. closing a cdc-acm device from userspace) may lead to wrong interpretation of further received notifications, in case the index is not 0 when urb unlink happens (i.e. when parts of a notification already have been transferred). On the device side there is no "reset" of the notification transimission and thus we would get out of sync with the device.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
