Subject: Re: [PATCH v2 3/3] tracing/kprobes: Use APIs that matches symbols without .XXX suffix

A fresher's eye, I met sometime when try to build a livepatch module and found some mistake caused by ".constprop.0" ".part.0" which is generated by GCC.
These section with such suffixes is special and sometime the symbol st_value is quite different. What is these kind of section (or symbol) use for?
