[PATCH 04/16] dyndbg: rename __verbose section to __dyndbg

From: Jim Cromie
Date: Fri Jun 05 2020 - 12:29:07 EST


dyndbg populates its callsite info into __verbose section, change that
to a more specific and descriptive name, __dyndbg.

Also, per checkpatch:
simplify __attribute(..) to __section(__dyndbg) declaration.
