Bug Description

LRU dump/restore is not supported (new feature available in XtraDB-9).

To reproduce it:

select * from information_schema.XTRADB_ADMIN_COMMAND /*!XTRA_LRU_DUMP*/;

It will create a file 'ib_lru_dump' in datadir. Xtrabackup started just after will not include it.

Vadim, is this at all on your radar or shall I reassign?

Actually with closer look it is trickier than I expected.

I would want to copy 'ib_lru_dump' outside of "FLUSH TABLES WITH READ LOCK" ,
but that requires some changes in logic.

So for proper implementation it should be assigned to someone else.

Important to take into account it should work for both modes: local-copy and stream.
And as I mentioned above - it should be done outside of FLUSH TABLES WITH READ LOCK section.
