From: Lars Ellenberg Date: Wed, 11 Jan 2012 08:43:25 +0000 (+0100) Subject: drbd: make OOS_HANDED_TO_NETWORK its own case X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=6d49e101fd3d3dbd525564923a82fb8a66676420;p=openwrt%2Fstaging%2Fblogic.git drbd: make OOS_HANDED_TO_NETWORK its own case OOS_HANDED_TO_NETWORK should not be grouped with the various *_CANCELED/*_FAILED cases. Also, not only clear the RQ_NET_QUEUED flag, but also mark it RQ_NET_DONE, so it can be distinguished from a local-only request even after that.
