Description:
Even though the buffer pool structures are interleaved after the patch
contributed in bug #72811, there are some other shared data structures
that may benefit from interleaving. For example:

- name and id table hashes in the data dictionary

- the tablespace cache (fil_system)

- the lock system (lock_sys)

- the log buffer

- etc.

How to repeat:
Inspect code for shared InnoDB data structures that may potentially have non-trivial size. Note lack of NUMA support.

Hi Kaamos,

I have checked code, not thoroughly though, and it seems to me that you are right.

This is justified feature request !!!!
