Hi Greg,
Following are the rest of previous patchset rebased on latest staging-next
and reordered to avoid breaking bisecability. Please help to queue them.
[Resend again to fix up patch authorship of my own. Sorry for the noise...]
Thanks,
Tao
Liu Xuezhao (1):
staging/lustre/obdclass: add obd_target.h
Peng Tao (2):
staging/lustre: fix build on non-x86
staging/lustre: fix Kconfig bool defaults

1.7.9.5
From: Liu Xuezhao <[email protected]>
Move some server-side data structures form obd.h to obd_target.h. To
remove some code dependencies use HAVE_SERVER_SUPPORT to protect some
llog/fsfilt_* functions.

Why is the default for this going to be 'y'? That should only be for
things that keep the machine from booting.
If this is something you always want to do, then why make it an option
at all?
Given that there is no documentation for what this option is, and why
people should always turn it on, I can't accept this patch, sorry.

I was hoping to use the config option to control over whether the
translation code need to be compiled. After checking other Makefiles,
I found that I can just use ifeq clause in Makefile to do it. So this
config option can be deleted. I will send updated patch.
