As Documentation/s390/s390dbf.txt states quite clearly, using any pointer in sprinf-formatted s390dbf debug entries is dangerous. The pointers are dereferenced whenever the trace file is read from. So if the referenced data has a shorter life-time than the trace file, any read operation can result in a use-after-free. So rip out all hazardous use of indirect data, and replace any usage of dev_name() and such by the Bus ID number. Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S.

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.
