neighbor page
Any page in the same extent as a particular page. When a page is selected to be flushed, any neighbor pages that are dirty are typically flushed as well, as an I/O optimization for traditional hard disks. In MariaDB 5.6 and up, this behavior can be controlled by the configuration variable innodb-flush-neighbors; you might turn that setting off for SSD drives, which do not have the same overhead for writing smaller batches of data at random locations.
