| |
2.6.33-stable review patch. If anyone has any objections, please let me know.
------------------
From: NeilBrown <neilb@suse.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.
