From 95c65ae1933446eaaf9de0c0161b883fb74652f3 Mon Sep 17 00:00:00 2001 From: Andrea Bolognani Date: Tue, 1 Mar 2016 19:53:37 +0100 Subject: [PATCH] hostdev: Rename hostdev_mgr -> mgr We're in the hostdev module, so mgr is not an ambiguous name, and in fact it's already used in some cases. Switch all the code over. Take the chance to shorten declaration of virHostdevIsPCINodeDeviceUsedData structures. --- src/util/virhostdev.c | 157 +++++++++++++++++++++--------------------- 1 file changed, 77 insertions(+), 80 deletions(-) diff --git a/src/util/virhostdev.c b/src/util/virhostdev.c index 8f66ea0b66..206de87b80 100644 --- a/src/util/virhostdev.c +++ b/src/util/virhostdev.c @@ -55,7 +55,7 @@ static void virHostdevManagerDispose(void *obj); static virHostdevManagerPtr virHostdevManagerNew(void); struct virHostdevIsPCINodeDeviceUsedData { - virHostdevManagerPtr hostdev_mgr; + virHostdevManagerPtr mgr; const char *domainName; const bool usesVfio; }; @@ -66,7 +66,7 @@ static int virHostdevIsPCINodeDeviceUsed(virPCIDeviceAddressPtr devAddr, void *o int ret = -1; struct virHostdevIsPCINodeDeviceUsedData *helperData = opaque; - other = virPCIDeviceListFindByIDs(helperData->hostdev_mgr->activePCIHostdevs, + other = virPCIDeviceListFindByIDs(helperData->mgr->activePCIHostdevs, devAddr->domain, devAddr->bus, devAddr->slot, devAddr->function); if (other) { @@ -469,7 +469,7 @@ virHostdevNetConfigReplace(virDomainHostdevDefPtr hostdev, * For upgrade purpose: * To an existing VM on QEMU, the hostdev netconfig file is originally stored * in cfg->stateDir (/var/run/libvirt/qemu).
