So I added this to the commit log:

Committer tests:

Tests 79 onwards are shell tests:

Before:

  # perf test --skip 1,2,81,82,84,88,90
   1: vmlinux symtab matches kallsyms                                 : Skip (user override)
   2: Detect openat syscall event                                     : Skip (user override)
   3: Detect openat syscall event on all cpus                         : Ok
   4: Read samples using the mmap interface                           : Ok
   5: Test data source output                                         : Ok

  89: Check Arm CoreSight trace data recording and synthesized samples: Skip
  90: Check open filename arg using perf trace + vfs_getname          : FAILED!
