From fb0466c3ae7f1c73f70072af8fd27ac166908a2f Mon Sep 17 00:00:00 2001 From: Eric Van Hensbergen Date: Wed, 17 Oct 2007 14:31:07 -0500 Subject: 9p: fix bad kconfig cross-dependency This patch moves transport dynamic registration and matching to the net module to prevent a bad Kconfig dependency between the net and fs 9p modules.
