Currently, rcutorture groups runs in batches, building each scenario in a given batch, then invoking qemu to run all the kernels in the batch. Of course, if a given scenario's kernel fails to build, there is no qemu run for that scenario. And if all of the kernels in a given batch fail to build, there are no runs, and rcutorture immediately starts on the next batch. But not if --jitter has been specified, which it is by default. In this case, the jitter scripts are started unconditionally, and rcutorture waits for them to complete, even though there are no kernels to run. This commit therefore checks for this situation, and refuses to start jitter unless at least one of the kernels in the batch built successfully. This saves substantial time when all scenarios' kernels fail to build, particularly if a long --duration was specified. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
