From 7c73393acfcce11a8d8ee661e08bae24fc17af61 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven <arjan@linux.intel.com> Date: Mon, 26 Jan 2009 18:58:11 -0800 Subject: [PATCH] ide/net: flip the order of SATA and network init
this patch flips the order in which sata and network drivers are initialized.
SATA probing takes quite a bit of time, and with the asynchronous infrastructure other drivers that run after it can execute in parallel. Network drivers do tend to take some real time talking to the hardware, so running these later is a good thing (the sata probe then runs concurrent)
This saves about 15% of my kernels boot time.
Both Dave and Jeff acked this patch and suggested it should go via the async tree.
