| |
From: "Steven Rostedt (Google)" <rostedt@goodmis.org>
Instead of open coding a __dynamic_array() with a fixed length (which defeats the purpose of the dynamic array in the first place). Use the new __vstring() helper that will use a va_list and only write enough of the string into the ring buffer that is needed.
