This is a followup to
v1: https://lists.gnu.org/archive/html/qemu-devel/2019-01/msg04173.html
Changed in v2:
- Fix safety of QXL logging
- Handle format specifier macros is a more reliable manner
- Fix trace-events files missing newline
- Remove use of %m formats
Daniel P. Berrangé (4):
display: ensure qxl log_buf is a nul terminated string
trace: enforce that every trace-events file has a final newline
trace: forbid use of %m in trace event format strings
trace: add ability to do simple printf logging via systemtap
