Bug Description

[In:/doc/percona-server/5.7/performance/aio_page_requests.html]

This documentation page is unclear on two things:
- the feature is mostly infrastructure in the code, i.e. it enables other InnoDB parts to submit merged I/O requests - as such it's mostly invisible to user
- the only InnoDB code that makes uses of this feature is linear readahead - that is the only part that is visible to users

The link to http://yoshinorimatsunobu.blogspot.lt/2013/10/making-full-table-scan-10x-faster-in.html is misleading too, as this feature by itself does not make full table scans 10x faster
