Description:
Bug #36942 removed this output from SHOW ENGINE INNODB STATUS unless UNIV_DEBUG is defined:

"Total number of lock structs in row lock hash table %lu"

This change did not follow the deprecated feature process, so it may unexpectedly break applications that parse the output.

How to repeat:
SHOW ENGINE INODB STATUS and look for the missing output.

Suggested fix:
Provide the output but with zero values, so no work is required to generate them. Document that they will be zero unless the server is compiled with UNIV_DEBUG.

Decide whether to deprecate this part of the output and if yes, follow the deprecation process and timeline. I don't think that this is necessary - zero output is sufficient.
