Description:
In the function：row_truncate_table_for_mysql
I cleared all the adaptive hashes at step nine：
err = SysIndexIterator().for_each(dropIndex);
Why do you have to clean up again？
fil_reinit_space_header_for_table
  buf_LRU_flush_or_remove_pages
    buf_LRU_drop_page_hash_for_tablespace
     
   

How to repeat:
Inactive code

Suggested fix:
I found that I had cleared all the adaptive hash data when I dropped the index.
Adaptive hashing is built on index.

Hi Mr. chen,

Thank you for your bug report.

However, the code that you are analysing is from an old release. If you look a the code fromt our latest release, you will notice that this inactive code has been removed long time ago.

Not a bug.
