Hi,

Do you also have Kconfig patches for DLM needing SYSFS
and DLM needing CONFIG_NET ?

My original reply to this seemed to disappear into my email system
somewhere, so apologies if this is the second copy you get.

The DLM shouldn't depend upon SYSFS at all. I believe that its perfectly
ok whether or not thats compiled in. There is a patch relating to the
Kconfig for DLM which is in my -nmw tree:
Hm, OK.  Apparently I meant CONFIGFS instead of SYSFS.

The Kconfig for DLM in Linus' current tree says:
	select CONFIGFS_FS

so I don't know what else is needed.... its the same in -nmw as that bit
hasn't changed.

http://www.kernel.org/git/?p=linux/kernel/git/steve/gfs2-2.6-nmw.git;a=commitdiff;h=8758fbc8724c2da8a6a062f2b61d79c8f2a55c5f

This applies after the patch adding the TCP communications layer to DLM
which is also in -nmw. The patches in -nmw (next merge window) are a
superset of the ones I just requested that Linus pull since it contains
the newer features and more involved bug fixes and clean ups.

I believe that the Kconfig in -nmw is correct for DLM, though I'm
willing to be proved wrong. I'm also copying in Patrick in case he wants
to comment further as its more his area than mine,
I applied just that one patch to 2.6.19-rc6-git10 (which may or may not
be sufficient -- please say) and built with my previously failing config file.
You'll need the patch:
http://www.kernel.org/git/?p=linux/kernel/git/steve/gfs2-2.6-nmw.git;a=commitdiff;h=4a28fda50d864ede7d2724723949407e0e4043b8
as well. I'm also slightly surprised that you managed to get the errors
that you did, since most of those symbols appear to be networking
related and the DLM depends on INET which is clearly not set since NET
is not set.

Thanks, I'll apply that patch also and test again.

Part of the problem (IMO) is that kconfig s/w doesn't follow dependency
chains when applying "select"s.

It still fails with:

Which of the various methods (oldconfig, xconfig, menuconfig, etc) did
you use to generate this config?

make randconfig
