+Subject: [PATCH] PR28778: gcc warning tweak for sprintf precision parameter
+
+A precision=-1 sentinel value got interpreted as UINT_MAX in a
+context, leading to diagnostics like:
+
+/usr/share/systemtap/runtime/vsprintf.c:341:23: error: 'strnlen' specified bound 4294967295 may exceed maximum object size 2147483647 [-Werror=stringop-overread]
+
+Adding a clamp_t() around the parameter field to keep it limited to
+STP_BUFFER_SIZE (8K by default), which is apprx. the limit for a
+single printf.
