This commit includes the grace-period sequence numbers at the beginning and end of each segment in the "Failure/close-call rcutorture reader segments" list. These are in hexadecimal, and only the bottom byte. Currently, only RCU is supported, with its three sequence numbers (normal, expedited, and polled). Note that if all the grace-period sequence numbers remain the same across a given reader segment, only one copy of the number will be printed. Of course, if there is a change, both sets of values will be printed. Because the overhead of collecting this information can suppress heisenbugs, this information is collected and printed only in kernels built with CONFIG_RCU_TORTURE_TEST_LOG_GP=y.

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.
