Subject: [PATCH 1/1] perf python: Fix binding linkage due to rename and move
of evsel__increase_rlimit()
The changes in ("perf evsel: Rename evsel__increase_rlimit to
rlimit__increase_nofile") ended up breaking the python binding that now
references the rlimit__increase_nofile function, add the util/rlimit.o
to the tools/perf/util/python-ext-sources to cure that.
This was detected by the 'perf test python' regression test:
$ perf test python
14: 'import perf' in python : FAILED!
$ perf test -v python
Couldn't bump rlimit(MEMLOCK), failures may take place when creating BPF maps, etc
14: 'import perf' in python :
--- start ---
test child forked, pid 2912462
python usage test: "echo "import sys ; sys.path.insert(0, '/tmp/build/perf-tools-next/python'); import perf" | '/usr/bin/python3' "
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: /tmp/build/perf-tools-next/python/perf.cpython-311-x86_64-linux-gnu.so: undefined symbol: rlimit__increase_nofile
test child finished with -1
---- end ----
'import perf' in python: FAILED!
