-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.

-PR28804: tune default stap -s ## buffer size on small RAM machines

-Insert a forgotten division by num_online_cpu() to adjust downward the
-calculated bufsize.  Tweak normal defaults back to 128 * 2 * 64K
-(16MB) per CPU, as the stap man page indicates.  This may need further
-tweaking when balancing against staprun consumption performance, but
-at least we have the docs lined up with the code at the moment.

- pointer instead of lambdas instead of ptr_fun<>
-
-Saving 2 lines in ltrim/rtrim is probably not a good reason to drop
-compatibility with the RHEL6 system compiler.  Actually declaring a
-named function and passing the function pointer is compatible with
-everything.
