Hello!
Running rcutorture scenario TREE01 on next-20240820 on a dual-socket x86
system (and for that matter on my laptop) got me this warning during boot:
sysfs: cannot create duplicate filename '/devices/virtual/workqueue/scsi_tmf_1073822488'
The number at the end varies from run to run.
Bisection landed here:
b188c57af2b5 ("workqueue: Split alloc_workqueue into internal function and lockdep init")
My reproducer is to run this at the top of the Linux-kernel file tree:
tools/testing/selftests/rcutorture/bin/kvm.sh --allcpus --duration 1m --configs "2*TREE01" --trust-make
Reverting this commit on top of next-20240820 gets me clean runs.
I cannot see how the patch would make this happen, but then again,
I don't know this code at all well.
Thoughts?
Thanx, Paul
