commit: bf572541ab44240163eaa2d486b06f306a31d45a From: NeilBrown <[email protected]> Date: Wed, 12 Jan 2011 09:03:35 +1100 Subject: [PATCH] md: fix regression with re-adding devices to arrays with no metadata
Commit 1a855a0606 (2.6.37-rc4) fixed a problem where devices were re-added when they shouldn't be but caused a regression in a less common case that means sometimes devices cannot be re-added when they should be. In particular, when re-adding a device to an array without metadata we should always access the device, but after the above commit we didn't. This patch sets the In_sync flag in that case so that the re-add succeeds. This patch is suitable for any -stable kernel to which 1a855a0606 was applied.
