The openat2(2) syscall was added in v5.6.  Add support for openat2 to the
audit syscall classifier and for recording openat2 parameters that cannot
be captured in the syscall parameters of the SYSCALL record.

Supporting userspace code can be found in
https://github.com/rgbriggs/audit-userspace/tree/ghau-openat2

Supporting test case can be found in
https://github.com/linux-audit/audit-testsuite/pull/103

Richard Guy Briggs (3):
  audit: replace magic audit syscall class numbers with macros
  audit: add support for the openat2 syscall
  audit: add OPENAT2 record to list how

Well, that was a bit premature...  Commit descriptions in each of the
patches might be a good idea...  Somehow they got dropped from V1.  I
guess they seemed obvious to me.  :-)    Changelog might be a nice
addition too...  Sorry for the noise.
