From f0df33bcab4b687f0f18b9ebd69d374642e46a0e Mon Sep 17 00:00:00 2001 From: Michal Feix Date: Sun, 30 Jul 2006 03:03:32 -0700 Subject: [PATCH] [PATCH] nbd: Abort request on data reception failure When reading from nbd device, we need to receive all the data after receiving reply packet from the server - otherwise such request will never be ended. If socket is closed right after accepting reply control packet and in the middle of waiting for read data, nbd_read_stat() returns NULL and nbd_end_request() is not called. This patch fixes it.
