The core function always passes the data of request to the callback of listener in any case. Additionally, the listener can maintain the lifetime of data by reference count. In character device, no need to duplicate the payload of request anymore to copy it to user space. This commit extends the lifetime of data to obsolete duplication of payload for request in character 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. 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.
