Subject: [PROTO] send MSG_STOP_ACK before everything stops
X-Git-Tag: Tizen_SDK_2.3~176
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3dc7f81225fb87f63ff131fad756394f35188a9f;p=platform%2Fcore%2Fsystem%2Fswap-manager.git

[PROTO] send MSG_STOP_ACK before everything stops

MSG_STOP_ACK is sent right after MSG_STOP received.
If an error occurs during stop it is reported via MSG_ERROR.
