Comment by Marko Mäkelä [ 2022-02-11 ]

The function was renamed to LinuxAIOHandler::collect() in 10.2.

Searches for InnoDB: Failing assertion: slot only returned unrelated crashes in 10.2 or later (with slot_rec or a slot in a ROW_FORMAT=COMPRESSED page), related to encryption recovery failures that were probably fixed in late 2018 or early 2019. So, it looks like this problem never affected 10.2 or later versions.

10.0 and 10.1 have already reached their end of life.
