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

Percona now uses JIRA for bug reports so this bug report is migrated to: https://jira.percona.com/browse/PS-1133
