ccw "busid" should always be NUL-terminated, as evident from e.g. get_ccwdev_by_busid doing "return (strcmp(bus_id, dev_name(dev)) == 0)". Replace all strncpy initializing busid with strlcpy. This fixes the following gcc 8 warnings: drivers/s390/scsi/zfcp_aux.c:104:2: warning: 'strncpy' specified bound 20 equals destination size [-Wstringop-truncation] strncpy(busid, token, ZFCP_BUS_ID_SIZE); drivers/s390/block/dasd_eer.c:316:2: warning: 'strncpy' specified bound 10 equals destination size [-Wstringop-truncation] strncpy(header.busid, dev_name(&device->cdev->dev), DASD_EER_BUSID_SIZE); drivers/s390/block/dasd_eer.c:359:2: warning: 'strncpy' specified bound 10 equals destination size [-Wstringop-truncation] strncpy(header.busid, dev_name(&device->cdev->dev), DASD_EER_BUSID_SIZE); drivers/s390/block/dasd_devmap.c:429:3: warning: 'strncpy' specified bound 20 equals destination size [-Wstringop-truncation] strncpy(new->bus_id, bus_id, DASD_BUS_ID_SIZE); Acked-by: Stefan Haberland <sth@linux.ibm.com> Acked-by: Steffen Maier <maier@linux.ibm.com> Reviewed-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Vasily Gorbik <gor@linux.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
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.
