Date: Tue, 29 Apr 2008 13:34:54 +1000 From: NeilBrown <neilb@...e.de> To: Andrew Morton <akpm@...ux-foundation.org> Cc: linux-raid@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 002 of 9] md: Skip all metadata update processing when using external metadata. All the metadata update processing for external metadata is on in user-space or through the sysfs interfaces, so make "md_update_sb" a no-op in that case.
