[Qemu-devel] [PATCH] trace: add qemu mutex lock and unlock trace events

2017-04-24 Thread Jose Ricardo Ziviani
These trace events were very useful to help me to understand and find a reordering issue in vfio, for example: qemu_mutex_lock locked mutex 0x10905ad8 vfio_region_write (0001:03:00.0:region1+0xc0, 0x2020c, 4) qemu_mutex_unlock unlocked mutex 0x10905ad8 qemu_mutex_lock locked mutex 0x10905ad8
