[lustre-devel] [PATCH 00/24] lustre - more cleanups including module reduction.

[NeilBrown <neilb@suse.com>]

Here are a bunch more cleanups that will appear in my lustre-testing
tree shortly.

The interesting stuff is some enhancements to kbuild to let us
build modules from multiple directories.
I've used that to clean up the build of ptlrpc+ldlm and to
merge libcfs and lnet into the one module - I've left the lnds
separate.

I've haven't progressed further in lustre because I'm not sure which -
if any - modules are also used by the server.
I'd rather shared code was in a separate module to client-only.

Which parts of lustre/lustre/* are also used by server?

After that, it is all fairly simple cleanups.

I plan to submit the kbuild stuff upstream next week.

Thanks,
NeilBrown
