trace: avoid SystemTap "char const" warnings
SystemTap's dtrace(1) produces the following warning when it encounters "char const" instead of "const char": Warning: /usr/bin/dtrace:trace-dtrace-root.dtrace:66: syntax error near: probe flatview_destroy_rcu Warning: Proceeding as if --no-pyparsing was given. This is a limitation in current SystemTap releases. I have sent a patch upstream to accept "char const" since it is valid C: https://sourceware.org/ml/systemtap/2018-q1/msg00017.html In QEMU we still wish to avoid warnings in the current SystemTap release. It's simple enough to replace "char const" with "const char". I'm not changing the documentation or implementing checks to prevent this from occurring again in the future. The next release of SystemTap will hopefully resolve this issue. Cc: Daniel P. Berrange <berrange@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Daniel P.
