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
