I noticed that this function uses a lot of kernel stack when the "latent entropy" plugin is enabled: drivers/isdn/hardware/eicon/message.c: In function 'sig_ind': drivers/isdn/hardware/eicon/message.c:6113:1: error: the frame size of 1168 bytes is larger than 1152 bytes [-Werror=frame-larger-than=] We currently don't warn about this, as we raise the warning limit to 2048 bytes in mainline, but I'd like to lower that limit again in the future, and this function can easily be changed to be more efficient and avoid that warning, by making some of its local variables 'const'.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
