From 9ee0cb201e6bfe03549a649fd165a85cfed34d05 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Sun, 10 Feb 2013 23:12:45 +0100 Subject: block-migration: fix blk_mig_save_dirty_block() return value checking Commit 43be3a25c931a7f61a76fbfc9d35584cbfc5fb58 changed the blk_mig_save_dirty_block() return code handling. The function's doc comment says: /* return value: * 0: too much data for max_downtime * 1: few enough data for max_downtime */ Because of the 1 return value, callers must check for ret < 0 instead of just: if (ret) { ... } We do not want to bail when 1 is returned, only on error.
