From ef2f80ff7325b2c1888ff02ead28957b5840bf51 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 17 May 2010 11:27:00 +1000 Subject: [PATCH] md/linear: avoid possible oops and array stop Since commit ef286f6fa673cd7fb367e1b145069d8dbfcc6081 it has been important that each personality clears ->private in the ->stop() function, or sets it to a attribute group to be removed. linear.c doesn't. This can sometimes lead to an oops, though it doesn't always. Suitable for 2.6.33-stable and 2.6.34.
