Arnaldo Carvalho de Melo 005438a8ee perf trace: Support 'strace' syscall event groups 
I.e.:

  $ cat ~/share/perf-core/strace/groups/file
  access
  chmod
  creat
  execve
  faccessat
  getcwd
  lstat
  mkdir
  open
  openat
  quotactl
  readlink
  rename
  rmdir
  stat
  statfs
  symlink
  unlink
  $

Then, on a quiet desktop, try running this and then moving your mouse to
see the deluge of mouse related activity:

  # perf probe 'vfs_getname=getname_flags:72 pathname=filename:string'
  Added new event:
    probe:vfs_getname    (on getname_flags:72 with pathname=filename:string)

  You can now use it in all perf tools, such as:

	perf record -e probe:vfs_getname -aR sleep 1
  #
  # trace --ev probe:vfs_getname --filter-pids 2232 -e file
   0.042 (0.042 ms): mousetweaks/2235 open(filename: 0x14e3910, mode: 438                                   ) ...
   0.042 (        ): probe:vfs_getname:(ffffffff812230bc) pathname="/home/acme/.icons/Adwaita/cursors/xterm")
   0.100 (0.100 ms): mousetweaks/2235  ... [continued]: open()) = -1 ENOENT No such file or directory
   0.142 (0.018 ms): mousetweaks/2235 open(filename: 0x14c3c10, mode: 438                                   ) ...
   0.142 (        ): probe:vfs_getname:(ffffffff812230bc) pathname="/home/acme/.icons/Adwaita/index.theme")
   0.192 (0.069 ms): mousetweaks/2235  ... [continued]: open()) = -1 ENOENT No such file or directory
   0.230 (0.017 ms): mousetweaks/2235 open(filename: 0x14c3c10, mode: 438                                   ) ...
   0.230 (        ): probe:vfs_getname:(ffffffff812230bc) pathname="/usr/share/icons/Adwaita/cursors/xterm")
   0.253 (0.041 ms): mousetweaks/2235  ... [continued]: open()) = 14
   0.459 (0.008 ms): mousetweaks/2235 open(filename: 0x14e3910, mode: 438                                   ) ...
   0.459 (        ): probe:vfs_getname:(ffffffff812230bc) pathname="/home/acme/.icons/Adwaita/cursors/left_side")
   0.468 (0.017 ms): mousetweaks/2235  ... [continued]: open()) = -1 ENOENT No such file or directory

Need to combine that raw_syscalls:sys_enter(open) + probe:vfs_getname +
raw_syscalls:sys_exit(open) sequence...

Now, if you're bored, please write some more syscall groups, like the ones
in 'strace' and send it our way :-)
