Merge branch 'rcu/misc' into next

2025-11-30T21:20:33Z

- In order to prepare the layout for nohz_full work deferral to user exit, the context tracking state must shrink the counter of transitions to/from RCU not watching. The only possible hazard is to trigger wrap-around more easily, delaying a bit grace periods when that happens. This should be a rare event though. Yet add debugging and torture code to test that assumption. - Fix memory leak on locktorture module - Annotate accesses in rculist_nulls.h to prevent from KCSAN warnings. On recent discussions, we also concluded that all those WRITE_ONCE() and READ_ONCE() on list APIs deserve appropriate comments. Something to be expected for the next cycle. - Provide a script to apply several configs to several commits with torture. - Allow torture to reuse a build directory in order to save needless rebuild time. - Various cleanups.

torture: Permit negative kvm.sh --kconfig numberic arguments

2025-11-07T12:57:38Z

This commit loosens the kvm.sh script's regular expressions to permit negative-valued Kconfig options, for example: --kconfig CONFIG_CMDLINE_LOG_WRAP_IDEAL_LEN=-1 Signed-off-by: Paul E. McKenney Signed-off-by: Frederic Weisbecker

rcutorture: Permit kvm-again.sh to re-use the build directory

2025-11-05T23:03:12Z

This commit adds "inplace" and "inplace-force" values to the kvm-again.sh "--link" argument, which causes the run's output to be placed into the build directory. This could be used to save build time if the machine went down partway into a run, but it can also be used to do a large number of builds, and run the resulting kernels concurrently even if the builds are based on different commits. A later commit will add this latter capability to kvm-series.sh in order to produce large speedups for branch-checking operations. Signed-off-by: Paul E. McKenney Signed-off-by: Frederic Weisbecker

torture: Add kvm-series.sh to test commit/scenario combination

2025-11-05T23:03:10Z

This commit adds a kvm-series.sh script that takes a list of scenarios and a list of commits, and then runs each scenario on all of the commits. A given scenario is run on all the commits before advancing to the next scenario to minimize build times. The successes and failures are summarized at the end of the run. Signed-off-by: Paul E. McKenney Signed-off-by: Frederic Weisbecker

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

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)
