[Qemu-devel] [PATCH 20/20] libqtest: Enable compile-time format string checking |
Date: |
Thu, 12 Jul 2018 13:12:21 +0200 |
qtest_qmp() & friends pass their format string and variable arguments
to qobject_from_vjsonf_nofail(). Unlike qobject_from_jsonv(), they
aren't decorated with GCC_FMT_ATTR(). Fix that to get compile-time
format string checking.
