From 643feae785781d0a309bc11bc553220fff46415a Mon Sep 17 00:00:00 2001 From: Laine Stump Date: Sun, 5 Aug 2012 02:45:04 -0400 Subject: [PATCH] conf: rename interface "usageCount" to "connections" I want to include this count in the xml output of networks, but calling it "connections" in the XML sounds better than "usageCount", and it would be better if the name in the XML matched the variable name. In a few places, usageCount was being initialized to 0, but this is unnecessary, because VIR_ALLOC_N zero-fills everything anyway. --- src/conf/network_conf.c | 2 -- src/conf/network_conf.h | 2 +- src/network/bridge_driver.c | 46 ++++++++++++++++++------------------- 3 files changed, 24 insertions(+), 26 deletions(-) diff --git a/src/conf/network_conf.c b/src/conf/network_conf.c index 666118c0ac..905c644d58 100644 --- a/src/conf/network_conf.c +++ b/src/conf/network_conf.c @@ -1137,7 +1137,6 @@ virNetworkDefParseXML(xmlXPathContextPtr ctxt) } if (forwardDev) { - def->forwardIfs[0].usageCount = 0; def->forwardIfs[0].dev = forwardDev; forwardDev = NULL; def->nForwardIfs++; @@ -1169,7 +1168,6 @@ virNetworkDefParseXML(xmlXPathContextPtr ctxt) def->forwardIfs[ii].dev = forwardDev; forwardDev = NULL; - def->forwardIfs[ii].usageCount = 0; def->nForwardIfs++; } } diff --git a/src/conf/network_conf.h b/src/conf/network_conf.h index 040d91229c..23f163202f 100644 --- a/src/conf/network_conf.h +++ b/src/conf/network_conf.h @@ -132,7 +132,7 @@ typedef struct _virNetworkForwardIfDef virNetworkForwardIfDef; typedef virNetworkForwardIfDef *virNetworkForwardIfDefPtr; struct _virNetworkForwardIfDef { char *dev; /* name of device */ - int usageCount; /* how many guest interfaces are bound to this device? */ + int connections; /* how many guest interfaces are connected to this device? */ }; typedef struct _virNetworkForwardPfDef virNetworkForwardPfDef; diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index ec99e4dceb..77b38d27e1 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -2914,10 +2914,11 @@ networkAllocateActualDevice(virDomainNetDefPtr iface) } else { /* pick an interface from the pool */ - /* PASSTHROUGH mode, and PRIVATE Mode + 802.1Qbh both require - * exclusive access to a device, so current usageCount must be - * 0.
