Date: Thu, 01 Jul 2010 10:42:57 -0700 From: Greg KH <gregkh@...e.de> To: linux-kernel@...r.kernel.org, stable@...nel.org Cc: stable-review@...nel.org, torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, NeilBrown <neilb@...e.de> Subject: [087/200] md/linear: avoid possible oops and array stop 2.6.34-stable review patch. If anyone has any objections, please let me know. ------------------ From: NeilBrown <neilb@...e.de> commit ef2f80ff7325b2c1888ff02ead28957b5840bf51 upstream. 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.
