Bug Description
I use Percona on top of ZFS, so I disable the doublewrite buffer since it's redundant and unnecessary. I do this with skip-innodb_
The new Percona 5.7.11-4 has added the new parallel doublewrite buffer feature and according to the log file (next line), this new buffer is being created.
[Note] InnoDB: Created parallel doublewrite buffer at /var/lib/
I don't think it's actually being used, since an "ls -l" in /var/lib/mysql shows a stale "last updated" timestamp for the xb_doublewrite file.
But it should not be created at all if doublewrites are disabled.
