Re: [PATCH 2/9] trace2: convert tr2tls_thread_ctx.thread_name from strbuf to char*

 struct tr2tls_thread_ctx {

 	uint64_t *array_us_start;
 	size_t alloc;
 	size_t nr_open_regions; /* plays role of "nr" in ALLOC_GROW */

Junio's suggestion in the linked E-Mail was to make this a "const char *".

Sorry, but in that linked E-Mail, I wasn't picking between "const
char *" and "char *" at all.  What I cared was *not* to keep a
long-term constant string in a member whose type is "struct strbuf".
