[PATCH 05/77] perf trace: Show comm/tid for augmented_syscalls

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <a...@redhat.com>

To get us a bit more like the sys_enter + sys_exit combo:

  # perf trace -e tools/perf/examples/bpf/augmented_syscalls.c,openat cat 
/etc/passwd > /dev/null
     0.000 (         ): openat(dfd: CWD, filename: 0x31b6dda8, flags: CLOEXEC)
     0.009 ( 0.009 ms): cat/3619 openat(dfd: CWD, filename: 0x31b6dda8, flags: 
CLOEXEC) = 3
     0.051 (         ): openat(dfd: CWD, filename: 0x31d75ce0, flags: CLOEXEC)
     0.054 ( 0.010 ms): cat/3619 openat(dfd: CWD, filename: 0x31d75ce0, flags: 
CLOEXEC) = 3
     0.539 (         ): openat(dfd: CWD, filename: 0xca71506b)
     0.543 ( 0.115 ms): cat/3619 openat(dfd: CWD, filename: 0xca71506b) = 3
  #

After:

  # perf trace -e tools/perf/examples/bpf/augmented_syscalls.c,openat cat 
/etc/passwd > /dev/null
     0.000 (         ): cat/4919 openat(dfd: CWD, filename: 0xc8358da8, flags: 
CLOEXEC)
     0.007 ( 0.005 ms): cat/4919 openat(dfd: CWD, filename: 0xc8358da8, flags: 
CLOEXEC) = 3
     0.032 (         ): cat/4919 openat(dfd: CWD, filename: 0xc8560ce0, flags: 
CLOEXEC)
     0.033 ( 0.006 ms): cat/4919 openat(dfd: CWD, filename: 0xc8560ce0, flags: 
CLOEXEC) = 3
     0.301 (         ): cat/4919 openat(dfd: CWD, filename: 0x91fa306b)
     0.304 ( 0.004 ms): cat/4919 openat(dfd: CWD, filename: 0x91fa306b) = 3
