[kernel test robot]

Hello,


we failed to run this new added test. not sure if we miss any dependencies?


below is full report FYI.


kernel test robot noticed "perf-sanity-tests.python_profiling_with_jitdump.fail" on:

commit: c9cd0c7e529e80e9be79867d2ebb874f67dbc35e ("perf test: Add python JIT dump test")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: perf-sanity-tests
version: 
with following parameters:

	perf_compiler: clang
	group: group-02


config: x86_64-rhel-9.4-bpf
compiler: gcc-14
test machine: 16 threads Intel(R) Core(TM) i7-13620H (Raptor Lake) with 32G memory

(please refer to attached dmesg/kmsg for entire log/backtrace)


If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
