Arnaldo Carvalho de Melo a9a187a749 perf trace: Beautify 'sync_file_range' arguments
Use existing beautifiers for the first arg, fd, assigned using the
heuristic that looks for syscall arg names and associates SCA_FD with
'fd' named argumes, and wire up the recently introduced sync_file_range
flags table generator.

Now it should be possible to just use:

   perf trace -e sync_file_range

As root and see all sync_file_range syscalls with its args beautified.

  Doing a syscall strace like session looking for this syscall, then run
  postgresql's initdb command:

  # perf trace -e sync_file_range
  <SNIP>
