Every mount a message is printed to the console:

Lustre: 16987:0:(gss_svc_upcall.c:1210:gss_init_svc_upcall()) Init channel is not opened by lsvcgssd, following request might be dropped until lsvcgssd is active

yet GSS is not enabled on this system. There is no benefit to printing this message and it should be turned into CDEBUG(D_SEC, ...) or somehow only printed if Kerberos or SSK are enabled.

Sebastien, could you please push a patch. I would personally just change it to a CDEBUG, but possibly this is useful to you, so you might have a better idea.
