[PATCH] block/rnbd: send_msg_close if any error occurs after send_msg_open

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Gioh Kim <gi-oh.kim@xxxxxxxxxxxxxxx>

After send_msg_open is done, send_msg_close should be done
if any error occurs and it is necessary to recover
what has been done.
