commite31c53a806upstream. The xfile/xmbuf shmem file descriptions are no longer as detailed as they were when online fsck was first merged, because moving to static strings in commit60382993a2("xfs: get rid of the xchk_xfile_*_descr calls") removed a memory allocation and hence a source of failure. However this makes encoding the description in the tracepoints sort of a waste of memory. David Laight also points out that file_path doesn't zero the whole buffer which causes exposure of stale trace bytes, and Steven Rostedt wonders why we're not using a dynamic array for the file path. I don't think this is worth fixing, so let's just rip it out.

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.
