[libvirt] [PATCH] qemu: kill some dead stores

Spotted by clang. The qemuConnectMonitor one is an outright bug, the other two are cosmetic. * src/qemu/qemu_monitor.c (qemuMonitorClose): Kill dead store. * src/qemu/qemu_driver.c (qemudDomainSaveImageStartVM): Likewise. (qemuConnectMonitor): Don't lose error status. --- src/qemu/qemu_driver.c | 2 -- src/qemu/qemu_monitor.c | 4 +--- 2 files changed, 1 insertions(+), 5 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 098f4da..57b8271 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1416,7 +1416,6 @@ qemuConnectMonitor(struct qemud_driver *driver, virDomainObjPtr vm) ret = qemuMonitorSetCapabilities(priv->mon); qemuDomainObjExitMonitorWithDriver(driver, vm); - ret = 0; error: if (ret < 0) qemuMonitorClose(priv->mon); @@ -6535,7 +6534,6 @@ qemudDomainSaveImageStartVM(virConnectPtr conn, wait_ret = qemudDomainSaveImageClose(fd, read_pid, &status); fd = -1; if (read_pid != -1) { - read_pid = -1; if (wait_ret == -1) { virReportSystemError(errno, _("failed to wait for process reading '%s'"), diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index f1494ff..2366fdb 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -685,8 +685,6 @@ cleanup: void qemuMonitorClose(qemuMonitorPtr mon) { - int refs; - if (!mon) return; @@ -706,7 +704,7 @@ void qemuMonitorClose(qemuMonitorPtr mon) mon->closed = 1; } - if ((refs = qemuMonitorUnref(mon)) > 0) + if (qemuMonitorUnref(mon) > 0) qemuMonitorUnlock(mon); } -- 1.7.2
