From: Peter Oberparleiter Date: Mon, 7 Dec 2009 11:51:17 +0000 (+0100) Subject: [S390] cio: introduce parent-initiated device move X-Git-Tag: v2.6.33-rc1~349^2~68 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5d6e6b6f6f3eac10a7f5a15e961bac3b36824d9d;p=pandora-kernel.git [S390] cio: introduce parent-initiated device move Change the initiative to update subchannel-ccw device associations to the subchannel: when there is an indication that the internal association no longer reflects the current hardware state, mark each affected subchannel as requiring attention. Once processing reaches a subchannel, determine the correct association for that subchannel at that time and perform the necessary device_move operations. This change fixes problems with the previous approach which would leave devices in an inconsistent state when a new hardware change occurred while a device_move was already scheduled.
