SubjectRe: [Kgdb-bugreport] [PATCH -mm v2] 2.6.23-rc4-mm1: kgdboe link errors
Randy,

This patch is fine, and I am committing it to the for_mm kgdb tree.

I am also adding the "depends on NET" to the KGDBOE_NOMODULE section,
which would otherwise to a select on KGDBOE. We have to cover the case
for KGDB as a module and not as a module.

Thanks,
Jason.
