rcutorture: Fix numeric "test" comparison in srcu_lockdep.sh

2026-03-30T19:48:13+00:00

This commit switches from "-eq" to "=" to handle the non-numeric
comparisons in srcu_lockdep.sh.  While in the area, adjust SRCU flavor
to improve coverage.

torture: Print informative message for test without recheck file

2026-03-30T19:48:13+00:00

If a type of torture test lacks a recheck file, a bash diagnostic is
printed, which looks like a torture-test bug.  This commit gets rid of
this false positive by explicitly checking for the file, invoking it if
it exists, otherwise printing an informative non-diagnostic message.

torture: Make hangs more visible in torture.sh output

2026-03-30T19:48:13+00:00

This commit labels "QEMU killed" lines so that they will be picked up
by torture.sh processing.

kvm-check-branches.sh: Remove in favor of kvm-series.sh

2026-03-30T19:48:13+00:00

The kvm-series.sh script is an order-of-magnitude optimization of
kvm-check-branches.sh, so remove the old script.

rcutorture: Add --kill-previous option to terminate previous kvm.sh runs

2026-01-04T10:51:14+00:00

When kvm.sh is killed, its child processes (make, gcc, qemu, etc.) may
continue running. This prevents new kvm.sh instances from starting even
though the parent is gone.

Add a --kill-previous option that uses fuser(1) to terminate all
processes holding the flock file before attempting to acquire it. This
provides a clean way to recover from stale/zombie kvm.sh runs which
sometimes may have lots of qemu and compiler processes still disturbing.

rcutorture: Prevent concurrent kvm.sh runs on same source tree

2026-01-04T10:50:59+00:00

Add flock-based locking to kvm.sh to prevent multiple instances from
running concurrently on the same source tree. This prevents build
failures caused by one instance's "make clean" deleting generated files
while another instance is building causing build failures.

The lock file is placed in the rcutorture directory and added to
.gitignore.

torture: Include commit discription in testid.txt

2026-01-01T08:44:37+00:00

Currently, the testid.txt file in the top-level directory of the
rcutorture results contains the output of "git rev-parse HEAD", which
just gives the full SHA-1 of the current commit.  This is followed by
the output of "git status", which is further followed by the output of
"git diff".  This works, but is less than helpful to human readers
scanning a list of commits.

This commit therefore instead uses "git show --oneline --no-patch HEAD",
which provides a short SHA-1, but also the names of any branches and
the commit's title.

As in strip the "#" and everything after it and *then* tokenize.

torture: Make kvm-series.sh give run numbers and totals

2026-01-01T08:44:36+00:00

The kvm-series.sh script can easily be convinced to run on the order of
1,000 guest OSes, so some sort of progress indicator would be helpful.
This commit therefore updates the "Starting" output lines to read as in
the following example, adding the ("3 of 4"):

Starting TREE02/1.7e0ad1b49057 using 8 CPUs (4 of 4) Sat Nov 8 10:51:06 PM PST 2025
