The CSD-lock-hold diagnostics from CONFIG_CSD_LOCK_WAIT_DEBUG are printed in nanoseconds as unsigned long longs, which is a bit obtuse for human readers when timing bugs result in negative CSD-lock hold times. Yes, there are some people to whom it is immediately obvious that 18446744073709551615 is really -1, but for the rest of us... Therefore, print these numbers as signed long longs, making the negative hold times immediately apparent. Reported-by: Rik van Riel <riel@surriel.com> Signed-off-by: Paul E.

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 reStructuredText 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.
