Re: git: 5169d4307eb9 - main - nfs: Fallback to GID_NOGROUP on no groups

Sigh...  I see why, and it seems straightforward to fix.  Could you please try the attached patch?  It is also available at: https://people.freebsd.org/~olce/0001-cred-crsetgroups-Throw-away-old-groups-before-crexte.patch .
 
Hopefully, this was the last problem to solve.  All patches in the series, except the "nfs, rpc: *" one, have been tested and actually used on my machines for weeks.  I however don't use NFS on a daily basis, and it is now pretty clear that I have a big problem in my NFS testing setup, or messed up the related tests (am still not sure).

If you can't test this patch or if you still have a problem after this one, then I'll just revert the series pending my re-testing in a correctly setup NFS environment.

Sorry to have dragged you in this debugging session, and thanks for your efforts and feedback.
