Minor suggestion: instead of putting these comments and hardwired
knowledge here, I'd suggest putting them adjacent to the list of
DUMP_COMPONENT #defines, creating a symbol along the lines of
DUMP_COMPONENTS_REQUIRING_TABLE_LOCK. That approach would make it
far more likely that somebody changing the list of DUMP_COMPONENT
elements in future would notice the possible need to adjust the
requires-lock list.
