As an example, if I do a 'make' from a top-level kernel directory, for
an in-tree build, modpost calls its read_symbols() with the whole list
of modules being built in-tree (debug printf added by me to demonstrate):
...
modpost: read_symbols(drivers/scsi/sata_sx4.o)
modpost: read_symbols(drivers/scsi/sata_via.o)
modpost: read_symbols(drivers/scsi/sata_vsc.o)

modpost: read_symbols(drivers/scsi/scsi_transport_fc.o)

But if I do the same thing out-of-tree using DKMS and M= notation, I
get only those modules built in the M= directory:
make: Entering directory `/home/mdomsch/bk/modinfo/linux-2.6-modinfo'
LD /var/lib/dkms/kernel_ppp_mppe/0.0.5/build/built-in.o
CC [M] /var/lib/dkms/kernel_ppp_mppe/0.0.5/build/ppp_generic.o

Building modules, stage 2.
MODPOST
modpost: read_symbols(vmlinux)
modpost: read_symbols(/var/lib/dkms/kernel_ppp_mppe/0.0.5/build/ppp_generic.o)
modpost: read_symbols(/var/lib/dkms/kernel_ppp_mppe/0.0.5/build/ppp_mppe.o)

LD [M] /var/lib/dkms/kernel_ppp_mppe/0.0.5/build/ppp_mppe.ko
make: Leaving directory `/home/mdomsch/bk/modinfo/linux-2.6-modinfo'
So my modules built out-of-tree don't get dependency info from
/lib/modules/${kernelver}/ as I would have hoped.
Thoughts?
Thanks,
Matt
