Description:
# bin/mysql -A information_schema -e 'select name, subsystem from innodb_metrics' | grep Buffer

buffer_LRU_single_flush_failure_count   Buffer
buffer_LRU_get_free_search      Buffer

The two above use "Buffer". All others use "buffer". Shouldn't these use "buffer" to be consistent?

How to repeat:
see above

Suggested fix:
change to "buffer"
