[Qemu-devel] [PATCH 0/4] Remove trailing double quote limitation and add virtio_set_status trace event

[Stefan Hajnoczi]

This series removes the tracetool parser limitation that format strings must
begin and end with double quotes.  In practice this means we need to work
around PRI*64 usage by adding dummy "" at the end of the line.  It's fairly
easy to solve this parser limitation and do away with the workarounds.

While we're at it, also add the virtio_set_status() trace event to properly
follow the lifecycle of virtio devices.
