Without the change `perf `hangs up on charaster devices. On my system
it's enough to run system-wide sampler for a few seconds to get the
hangup:
$ perf record -a -g --call-graph=dwarf
$ perf report
# hung
`strace` shows that hangup happens on reading on a character device
`/dev/dri/renderD128`
$ strace -y -f -p 2780484
strace: Process 2780484 attached
pread64(101</dev/dri/renderD128>, strace: Process 2780484 detached
It's call trace descends into `elfutils`:

The hangup happens because nothing in` perf` or `elfutils` checks if a
mapped file is easily readable.
The change conservatively skips all non-regular files.

Symbolize stack traces by creating a live machine. Add this
functionality to dump_stack and switch dump_stack users to use
it. Switch TUI to use it. Add stack traces to the child test function
which can be useful to diagnose blocked code.
Example output:
```
$ perf test -vv PERF_RECORD_

The test starts a workload and then opens events. If the events fail
to open, for example because of perf_event_paranoid, the gopipe of the
workload is leaked and the file descriptor leak check fails when the
test exits. To avoid this cancel the workload when opening the events
fails.

Fix a mkdir-induced usage count imbalance that tripped a umount_check() BUG while unmounting the lower filesystem. Commit f046fbb ("ecryptfs: use new start_creating/start_removing APIs") added a new dget() of the lower parent dir, in ecryptfs_mkdir(), but did not dput() the dentry before returning from that function. The BUG output as seen while running the eCryptfs test suite: $ ./run_tests.sh -b 131072 -c safe,destructive -f ext4 -K -t lp-926292.sh ...
