From 126925c090155f13e90b9e7e8c4010e96027c00a Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Tue, 7 Sep 2010 17:02:47 +1000 Subject: [PATCH] md: call md_update_sb even for 'external' metadata arrays. Now that we depend on md_update_sb to clear variable bits in mddev->flags (rather than trying not to set them) it is important to always call md_update_sb when appropriate. md_check_recovery has this job but explicitly avoids it for ->external metadata arrays. This is not longer appropraite, or needed. However we do want to avoid taking the mddev lock if only MD_CHANGE_PENDING is set as that is not cleared by md_update_sb for external-metadata arrays.
