Subject: RE: linux-next: Tree for Sep 19

Is it completely acceptable to have default configs that select menu entries 
but not their dependencies ? Since essentially earlier the select on 
SCSI_NETLINK select used to select NET but no longer does, so I'm wondering
 if this was an oversight earlier.  Is this something that's supposed to be 
automatically resolved ?

Yes, I have a patch sitting on my hard drive that makes LIBFCOE and TCM_QLA2XXX
and SCSI_BNX2X_FCOE depend on SCSI_FC_ATTRS, but I'm not entirely happy about
having to hunt these down (even with the help of kconfig warnings).

I'm pretty sure that I can fix these (above and build errors below), but
there is still a bunch of nasty kconfig warnings that I don't understand
and don't know how to fix:

(powerpc ppc64_defconfig) produced these warnings:

git bisect also points to the SCSI_NETLINK dependency commit for these (unless
I did the bisect incorrectly).

Does anyone have a clue on these?
Thanks.
