Hi,

I observed this some time ago - so this is not only Linux v5.19-rc1 related.

$ LC_ALL=C make -C tools/perf clean 2>&1 | tee ../make-log_perf-clean.txt
make: Entering directory '/home/dileks/src/linux-kernel/git/tools/perf'
 CLEAN   x86
 CLEAN   libtraceevent
 CLEAN   libapi
 CLEAN   libbpf
 CLEAN   libsubcmd
 CLEAN   libperf
 CLEAN   fixdep
 CLEAN   feature-detect
 CLEAN   python
 CLEAN   bpf-skel
 CLEAN   core-objs
 CLEAN   core-progs
 CLEAN   core-gen
 CLEAN   Documentation
make: Leaving directory '/home/dileks/src/linux-kernel/git/tools/perf'

$ git status -s
M tools/perf/util/unwind-libunwind-local.c
?? tools/perf/a.out

$ rm -v tools/perf/a.out
'tools/perf/a.out' deleted

$ git checkout -- tools/perf/util/unwind-libunwind-local.c

$ git status -s
[ empty ]

Thanks.

Regards,
