Subject: [PATCH 0/3] mincore() and IOCB_NOWAIT adjustments

I've collected the patches from the discussion for formal posting. The first
two should be settled already, third one is the possible improvement I've
mentioned earlier, where only in restricted case we resort to existence of page
table mapping (the original and later reverted approach from Linus) instead of
faking the result completely. Review and testing welcome.

The consensus seems to be going through -mm tree for 5.1, unless Linus wants
them alredy for 5.0.

Jiri Kosina (2):
  mm/mincore: make mincore() more conservative
  mm/filemap: initiate readahead even if IOCB_NOWAIT is set for the I/O

Vlastimil Babka (1):
  mm/mincore: provide mapped status when cached status is not allowed
