linux-next: manual merge of the block tree with Linus' tree

[Stephen Rothwell]

Hi all,

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

  fs/io_uring.c

between commits:

  4ea672ab694c ("io_uring: fix ltimeout unprep")
  b22fa62a35d7 ("io_uring: apply worker limits to previous users")

from Linus' tree and commit:

  d475a9a6226c ("io_uring: inline hot path of __io_queue_sqe()")
  c072481ded14 ("io_uring: mark cold functions")

from the block tree.

I fixed it up (see below) 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.

Stephen Rothwell
