This patch continues the optimize fast trace paths started in previous patch (trace/simple: seperate hot paths of tracing fucntions), which optimized the simple backend by moving its hot path to the header. Here, we apply the same pattern to the log, ftrace, and syslog backends. The fast path remains in the header with minimal inline checks, while the backend-specific logic is now handled in dedicated `_log_trace_vhost_commit()`, `_ftrace_trace_vhost_commit()`, and `_syslog_trace_vhost_commit()` functions in the .c file. While this doesn’t yield the same level of optimization as the simple backend , it improves performance on compilers where inlining is less reliable and reduces header bloat. This change also improves code organization: - All trace event checks are now centralized in headers - All backend logic is contained in clearly named functions in the .c file This makes the tracing infrastructure cleaner, more maintainable, and better optimized for diverse compiler behaviors.
