The hists__filter_entries() function is called when down arrow key is
pressed for navigating through the entries in TUI. It has a check for
filtering out entries that have very small overhead (under min_pcnt).
However it just assumed the entries are sorted by the overhead so when
it saw such a small overheaded entry, it just stopped navigating as an
optimization. But it's not true anymore due to new --fields and
--sort optoin behavior and this case users cannot go down to a next
entry if ther's an entry with small overhead in-between.

Currently, what the sort_entry does is just identifying hist entries
so that they can be grouped properly. However, with -F option
support, it indeed needs to sort entries appropriately to be shown to
users. So add ->sort() member to do it.

Until now the hpp and sort functions do similar jobs different ways.
Since the sort functions converted/wrapped to hpp formats it can do
the job in a uniform way.
The perf_hpp__sort_list has a list of hpp formats to sort entries and
the perf_hpp__list has a list of hpp formats to print output result.
To have a backward compatibility, it automatically adds 'overhead'
field in front of sort list. And then all of fields in sort list
added to the output list (if it's not already there).

I believe that passing pid (instead of tid) as the 3rd arg of the
machine__find*_thread() was to find a main thread so that it can
search proper map group for symbols. However with the map sharing

It fixes a bug when each thread has different name, it only reports a

Currently perf record doesn't propagate the exit status of a workload
given by the command line. But sometimes it'd useful if it's
propagated so that a monitoring script can handle errors
appropriately.
To do that, it moves most of logic out of the exit handlers and run
them directly in the __cmd_record(). The only thing needs to be done
in the handler is propagating terminating signal so that the shell can
terminate its loop properly when Ctrl-C was pressed. Also it cleaned
up the resource management code in record__exit().
With this change, perf record returns the child exit status in case of
normal termination and send signal to itself when terminated by signal.
Example run of Stephane's case:
$ perf record true && echo yes || echo no
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.013 MB perf.data (~589 samples) ]
yes
$ perf record false && echo yes || echo no
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.013 MB perf.data (~589 samples) ]
no
Jiri's case (error in parent):
$ perf record -m 10G true && echo yes || echo no
rounding mmap pages size to 17179869184 bytes (4194304 pages)
failed to mmap with 12 (Cannot allocate memory)
no
$ ulimit -n 6
$ perf record sleep 1 && echo yes || echo no
failed to create 'go' pipe: Too many open files
Couldn't run the workload!
no
And Peter's case (interrupted by signal):
$ while :; do perf record sleep 1; done
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.014 MB perf.data (~593 samples) ]

In output of perf sched map, any shortname of thread will be explained
at the first time when it appear.
Example:
*A0 228836.978985 secs A0 => perf:23032
*. A0 228836.979016 secs B0 => swapper:0
. *C0 228836.979099 secs C0 => migration/3:22
*A0 . C0 228836.979115 secs
A0 . *. 228836.979115 secs
But B0, which is explained as swapper:0 did not appear in the
left part of output. Instead, we use '.' as the shortname of
swapper:0. So the comment of "B0 => swapper:0" is not easy to
understand.
This patch clarify the output of perf sched map with not allocating
one letter-number shortname for swapper:0 and print ". => swapper:0"
as the explanation for swapper:0.
Example:
*A0 228836.978985 secs A0 => perf:23032
* . A0 228836.979016 secs . => swapper:0

It's defined in include/uapi/linux/prctl.h header.
Also it was never used in perf tool.

Combine all definitions into a common tools/include/linux/types.h and
kill the wild growth elsewhere. Move DECLARE_BITMAP to its proper
bitmap.h header.

So tools/ has been growing three, at a different stage of their

tools/include/ to the include path of virtio and liblockdep to pick the
shared header now.
