Linux kernel stable tree

Currently, the rcu_torture_pipe_update_one() writes the value (i + 1) to rp->rtort_pipe_count, then immediately re-reads it in order to compare it to RCU_TORTURE_PIPE_LEN. This re-read is pointless because no other update to rp->rtort_pipe_count can occur at this point. This commit therefore instead re-uses the (i + 1) value stored in the comparison instead of re-reading rp->rtort_pipe_count.

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.
