Subject: [linus:master] [perf pmu] a0c41caeba:
kmsg.sanitizer.direct_leak/__interceptor_malloc/perf_cpu_map__alloc/perf_cpu_map__empty_new/cpu_map__from_range/cpu_map__new_data/perf_event__fprintf_event_update
Hello,
kernel test robot noticed "kmsg.sanitizer.direct_leak/__interceptor_malloc/perf_cpu_map__alloc/perf_cpu_map__empty_new/cpu_map__from_range/cpu_map__new_data/perf_event__fprintf_event_update" on:
commit: a0c41caebab2fa224454d50dd4e29ae008ead25f ("perf pmu: Add CPU map for "cpu" PMUs")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[test failed on linus/master 18b44bc5a67275641fb26f2c54ba7eef80ac5950]
[test failed on linux-next/master 0ba5d07205771c50789fd9063950aa75e7f1183f]
in testcase: perf-test
version: perf-test-x86_64-git-1_20220520
with following parameters:
type: lkp
group: group-01
test-description: The internal Perf Test suite.
compiler: gcc-12
test machine: 224 threads 2 sockets Intel(R) Xeon(R) Platinum 8480+ (Sapphire Rapids) with 256G memory
(please refer to attached dmesg/kmsg for entire log/backtrace)
we also noticed there are 2 other "Direct leak" but exist on both this commit
and parent. (there are 3 "Indrect leak", but since exist on both this commit
and parent, we don't highlight below, details are in attached dmesg)
we are not sure enough the impact of those 2 other "Direct leak", which we will
check further if we can capture the first commit caused them. we just report
this difference we found in our tests FYI.

To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.
