Hello mtk

I've noticed "%e-%s.core" often gives something other than the filename and the name is truncated to 16 bytes:-

ThreadPoolServi-5.core
Chrome_InProcUt-5.core

This was set:
sysctl -w kernel.core_pattern="%e-%s.core"



In multithreaded applications it looks like %e is giving something other than the filename, perhaps a thread entry-point 
symbol name.

https://www.man7.org/linux/man-pages/man5/core.5.html

            %e  executable filename (without path prefix)

Could this be updated to:

            %e  executable filename or thread name truncated to 16 bytes

Cheers, Jonny
