| 2018-06-28 | QemuMutex: support --enable-debug-mutex | Paolo Bonzini | |
| We have had some tracing tools for mutex but it's not easy to use them for e.g. dead locks. Let's provide "--enable-debug-mutex" parameter when configure to allow QemuMutex to store the last owner that took specific lock. It will be easy to use this tool to debug deadlocks since we can directly know who took the lock then as long as we can have a debugger attached to the process. Reviewed-by: Emilio G.

| 2018-06-28 | qemu-thread: introduce qemu-thread-common.h | Peter Xu | |
| Introduce some hooks for the shared part of qemu thread between POSIX and Windows implementations. Note that in qemu_mutex_unlock_impl() we moved the call before unlock operation which should make more sense. And we don't need qemu_mutex_post_unlock() hook. Put all these shared hooks into the header files. It should be internal to qemu-thread but not for qemu-thread users, hence put into util/ directory. Reviewed-by: Emilio G.
