Subject: [PATCH 3/3] defs.h: fix breakage of compatibility of struct
symbol_table_data for extension modules
Commit <2fab8fbc0c4f> ("symbols: Implement install and remove operations
for mod_symname_hash") added new member variable mod_symname_hash in the
middle of struct symbol_table_date, which breaks compatibility of struct
symbol_table_data for extension modules. As the result, crash trace command
results in segmentation fault.
Fixes: 2fab8fbc0c4f ("symbols: Implement install and remove operations for mod_symname_hash")
