From 1c1876b0f433c9f5e6a6181ca725e31a6f9f9fed Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Sun, 20 Jul 2008 13:07:09 -0700 Subject: [PATCH] fastboot: make the raid autodetect code wait for all devices to init The raid autodetect code really needs to have all devices probed before it can detect raid arrays; not doing so would give rather messy situations where arrays would get detected as degraded while they shouldn't be etc. This is in preparation of removing the "wait for everything to init" code that makes everyone pay, not just raid users.
