Merge tag 'probes-fixes-v7.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull probes selftest fix from Masami Hiramatsu:

 - selftests/ftrace: Refactor eprobes test to fix argument checks

   Refactor the eprobes selftest to get more stable test result by using
   `sys_enter_chdir` instead of `openat` and filter for exact directory
   names

   This resolves test instability after the string pointer handling fix
