Subject: linux-next: manual merge of the block tree with the mm tree

Hi all,

FIXME: Add owner of second tree to To:
       Add author(s)/SOB of conflicting commits.

Today's linux-next merge of the block tree got a conflict in:

  io_uring/io_uring.c

between commit:

  d3329b3a9d72 ("mm: switch mm->get_unmapped_area() to a flag")

from the mm-unstable branhc of the mm tree and commit:

  624d801ce45b ("io_uring: move mapping/allocation helpers to a separate file")

from the block tree.

I fixed it up (I used the latter version of this file and applied the
following merge fix patch) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
