Whenever we disconnect a L2CAP connection, we would immediately report a disconnection event (EPOLLHUP) to the upper layer, without waiting for the response of the other device. This patch offers an option to wait until we receive a disconnection response before reporting disconnection event, by using the "how" parameter in l2cap_sock_shutdown(). Therefore, upper layer can opt to wait for disconnection response by shutdown(sock, SHUT_WR). This can be used to enforce proper disconnection order in HID, where the disconnection of the interrupt channel must be complete before attempting to disconnect the control channel.

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.
