   4 Subject: [PATCH] fastboot: make the raid autodetect code wait for all devices to init
   5
   6 The raid autodetect code really needs to have all devices probed before
   7 it can detect raid arrays; not doing so would give rather messy situations
   8 where arrays would get detected as degraded while they shouldn't be etc.
   9
  10 This is in preparation of removing the "wait for everything to init"
  11 code that makes everyone pay, not just raid users.
