torture: Add --do-normal parameter to torture.sh help text

2025-08-14T22:26:30Z

The --do-normal parameter was missing from the torture.sh script's help text, so this commit adds it. Hopefully better late than never! Signed-off-by: Paul E. McKenney

rcutorture: Fix jitter.sh spin time

2025-08-14T22:26:30Z

An embarrassing syntax error in jitter.sh makes for fixed spin time. This commit therefore makes it be variable, as intended, albeit with very coarse-grained adjustment. Signed-off-by: Paul E. McKenney

rcutorture: Remove SRCU-lite scenarios

2025-07-16T04:18:28Z

This commit prepares for the removal of SRCU-Lite by removing the SRCU-L rcutorture scenario that tests it. Both SRCU-lite and SRCU-fast provide faster readers by dropping the smp_mb() call from their lock and unlock primitives, but incur a pair of added RCU grace periods during the SRCU grace period. There is a trivial mapping from the SRCU-lite API to that of SRCU-fast, so there should be no transition issues. [ paulmck: Apply Christoph Hellwig feedback. ] Signed-off-by: "Paul E.

torture: Make torture.sh --allmodconfig testing fail on warnings

2025-07-16T04:14:04Z

Currently, the torture.sh --allmodconfig testing looks solely at the exit code from the kernel build, and thus fails to flag many compiler warnings. This commit therefore checks the kernel-build output for compiler diagnostics. Signed-off-by: Paul E. McKenney Signed-off-by: Neeraj Upadhyay (AMD)

torture: Add "ERROR" diagnostic for testing kernel-build output

2025-07-16T04:14:04Z

Some recent kernel-build failures have featured "ERROR", so this commit adds it to the list checked by kvm-build.sh. Signed-off-by: Paul E. McKenney Signed-off-by: Neeraj Upadhyay (AMD)

torture: Make torture.sh tolerate runs having bad kvm.sh arguments

2025-07-16T04:14:04Z

Currently, torture.sh assumes excessive levels of reviewer competence and thus fails to gracefully handle cases where it is tricked into giving kvm.sh invalid arguments. This commit therefore upgrades error handling to more gracefully handle this situation. Signed-off-by: Paul E. McKenney Signed-off-by: Neeraj Upadhyay (AMD)

torture: Add textid.txt file to --do-allmodconfig and --do-rcu-rust runs

2025-07-16T04:14:04Z

This commit causes the torture.sh --do-allmodconfig and --do-rcu-rust parameters to add testid.txt files to their results directories, thus allowing easier analysis of the results of a series of runs kicked off by "git bisect". Signed-off-by: Paul E. McKenney Signed-off-by: Neeraj Upadhyay (AMD)

torture: Extract testid.txt generation to separate script

2025-07-16T04:14:04Z

The kvm.sh script places a testid.txt file in the top-level results directory in order to identify the tree and commit that was tested. This works well, but there are scripts other than kvm.sh that also create results directories, and it would be good for them to also identify exactly what was tested. This commit therefore extracts the testid.txt generation to a new mktestid.sh script so that it can be easily used elsewhere. Signed-off-by: Paul E. McKenney Signed-off-by: Neeraj Upadhyay (AMD)

torture: Suppress "find" diagnostics from torture.sh --do-none run

2025-07-16T04:14:04Z

When torture.sh is told to do nothing, it produces a couple of distracting diagnostics from the "find" command: find: ‘’: No such file or directory find: ‘’: No such file or directory This is pointless chatter and could cause confusion. This commit therefore suppresses these diagnostics when there is nothing to find. Signed-off-by: Paul E. McKenney Signed-off-by: Neeraj Upadhyay (AMD)
