The scripts have calls to 'perf trace' that need to be converted to 'perf script', do it.
This problem was introduced in 133dc4c.

. Print message at script start telling how to get te summary
. Print the syscall name using the audit-lib-python package, if
installed
. Print the errno string
. Accept both pid (if numeric) or COMM name
Now it looks like this:
[root@emilia ~]# perf trace failed-syscalls-by-pid
Press control+C to stop and show the summary
^C
syscall errors:
comm [pid] count
------------------------------ ----------
automount [1670]
syscall: futex
err = ETIMEDOUT 39
irqbalance [1462]
syscall: openat
err = ENOENT 4
perf [7888]
syscall: lseek
err = ESPIPE 1
syscall: open
err = ENOENT 24
perf [7889]
syscall: ioctl
err = EINVAL 1
syscall: readlink
err = EINVAL 2
syscall: open
err = ENOENT 389
syscall: stat
err = ENOENT 141
syscall: lseek
err = ESPIPE 3
[root@emilia ~]#
[root@emilia ~]# perf trace failed-syscalls-by-pid 1670
Press control+C to stop and show the summary
^C
syscall errors:
comm [pid] count
------------------------------ ----------
automount [1670]
syscall: futex
err = ETIMEDOUT 2
[root@emilia ~]#
[root@emilia ~]#
[root@emilia ~]#
[root@emilia ~]# perf trace failed-syscalls-by-pid automount
Press control+C to stop and show the summary
^C
syscall errors for automount:
comm [pid] count
------------------------------ ----------
automount [1669]
syscall: futex
err = ETIMEDOUT 1
automount [1670]
syscall: futex
err = ETIMEDOUT 5

Adds a set of scripts that aggregate system call totals and system
call errors. Most are Python scripts that also test basic
functionality of the new Python engine, but there's also one Perl
script added for comparison and for reference in some new
Documentation contained in a later patch.
