[l-k people: please retain the CC to me or to linux-kbuild@torque.net,
which I read much more faithfully than l-k. Thx.]
We on linux-kbuild have been discussing link order for object files in
the kernel. Most of the time, the object files in a given directory
can be sorted, then duplicates removed, then linked ... but this fails
when one .initcall must happen before another.
MEC came up with a scheme for removing duplicate object file names yet
still providing link ordering for those objects that really need it.
As a side effect it documents the need, which is Good. So now we need
to get a list of those places.
Along with that, could we also get "wishlist" ordering -- the places
that currently don't use .initcall but might in the future? I'm
thinking of d/scsi, d/net and d/sound in particular.
My current list, including "wishlist":
* ppa and imm after other scsi hosts because they're removable
* buslogic before aha1542
* sym53c8xx before ncr53c8xx (just a guess -- is it true?)
* ncr53c406a before qlogic
* i2o-block after several SCSI hosts -- which ones?
* sbusfb before PCI framebuffers
* offb after atyfb and others -- which ones?
* vfb after all other framebuffers
I know for a fact that there are ordering issues hidden (and
undocumented, which is a Bad Thing) in d/net/Space.c and
d/sound/Makefile. Can someone please enumerate them? Thanks much.
