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

Hi Jens,

Today's linux-next merge of the block tree got a conflict in
drivers/ide/ide-atapi.c between several commit
626542ca2277961aaa64855206574f8ca4f360e3 ("ide-tape: change
IDE_AFLAG_IGNORE_DSC non-atomically") from the ide tree and commit
8f6205cd572fece673da0255d74843680f67f879 ("ide: dequeue in-flight
request") from the block tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.
