Hi Lluís,
I hit an issue testing the different backends with this series applied.

The simple trace writeout thread hangs when the 'quit' monitor command
is issued.  Do you see the same issue?

$ ./configure --target-list=x86_64-softmmu --enable-trace-backend=simple
$ make -j4
$ cat my-events 
bdrv_open_common
$ x86_64-softmmu/qemu-system-x86_64 -trace events=my-events
(qemu) quit
