We print a 256 byte event string into a buffer that is only 161
bytes long, this is clearly wrong:
drivers/scsi/gdth_proc.c: In function 'gdth_show_info':
drivers/scsi/gdth.c:3660:41: error: '%s' directive writing up to 255 bytes into a region of size between 141 and 150 [-Werror=format-overflow=]
sprintf(buffer,"Adapter %d: %s\n",
^~
/git/arm-soc/drivers/scsi/gdth.c:3660:13: note: 'sprintf' output between 13 and 277 bytes into a destination of size 161
sprintf(buffer,"Adapter %d: %s\n",
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
dvr->eu.async.ionode,dvr->event_string);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gcc calculates that the worst case buffer size would be 277 bytes,
so we can use that.

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.
