Re: [libvirt] [PATCH 4/5] Convert QEMU driver mutex into a rwlock

2009/10/14 Daniel P. Berrange <berrange@redhat.com>:

A number of driver API methods which acquire the driver mutex only ever used the driver object in a read-only fashion. All these uses are converted to call qemuDriverLockRO() allowing for greater concurrency.

* src/qemu/qemu_conf.h: s/Mutex/RWLock/ * src/qemu/qemu_driver.c: Add a qemuDriverLockRO() method and use  it anywhere that doesn't require a write lock on the driver ---

ACK. Matthias
