Subject: [linus:master] [perf symbols] ce4c8e7966:
 perf-sanity-tests.Test_data_symbol.fail

Greeting,

FYI, we sent a report when this commit was in linux-next/master:

https://lore.kernel.org/all/202302092156.c0b14693-oliver.sang@intel.com/

This commit has been merged to mainline and we still observe similar
failures, so we report again FYI.

We noticed perf-sanity-tests.Test_data_symbol.fail due to commit (built with gcc-11):

commit: ce4c8e7966f317ef2af896778b5fa9105a5cd351 ("perf symbols: Get symbols for .plt.got for x86-64")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

[test failed on linux-next/master 1acf39ef8f1425cd105f630dc2c7c1d8fff27ed1]

	perf_compiler: clang

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.
