linux-next: manual merge of the scsi-mkp tree with the libata tree

[Mark Brown]

Hi all,

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

  drivers/ata/libata.h

between commit:

  0ea84089dbf62 ("ata: libata-scsi: avoid Non-NCQ command starvation")

from the libata tree and commit:

  0db3f51839fe7 ("scsi: Change the return type of the .queuecommand() callback")

from the scsi-mkp 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.

Mark,

Thank you for the fix. It looks good.

Martin,

What do you want to do ? I can rebase the 2 ata patches involved with this
conflict and you can take them in the scsi tree (that should not generate
another conflict with libata). Or we just leave this as is and sync up our PRs
for 6.20 so that Linus is notified of the conflict by one of us ?
