linux-next: manual merge of the init tree with the block tree

linux-next: manual merge of the init tree with the block tree

[Stephen Rothwell]

Hi all,

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

  drivers/md/md.c

between commit:

  a564e23f0f99 ("md: switch to ->check_events for media change notifications")

from the block tree and commit:

  7e0adbfc20c5 ("md: rewrite md_setup_drive to avoid ioctls")

from the init 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.

This is now a conflict between the block tree and the vfs tree.

This is now a conflict between the vfs tree and Linus' tree.
