From 0d4ca600fcf5c5f3a0c195ccf37e989b83451dd4 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Sun, 10 Dec 2006 02:20:44 -0800 Subject: [PATCH] [PATCH] md: tidy up device-change notification when an md array is stopped An md array can be stopped leaving all the setting still in place, or it can torn down and destroyed. set_capacity and other change notifications only happen in the latter case, but should happen in both.
