Pkg xen devel - May 2014 - Bug#748953: blktap-dkms: Struct bio was changed in 3.14 breaking build

Package: blktap-dkms
Version: 2.0.93-0.2
Severity: serious
Justification: fails to build from source (but built successfully in the past)

The build fails on 3.14 kernel with the following error:

/var/lib/dkms/blktap/2.0.93/build/ring.c: In function
?blktap_ring_make_tr_request?:
/var/lib/dkms/blktap/2.0.93/build/ring.c:314:32: error: ?struct bio? has no
member named ?bi_sector?
  breq->u.tr.sector_number = bio->bi_sector;
                                ^
Struct bio was changed by commit
https://github.com/torvalds/linux/commit/4f024f3797c43cb4b73cd2c50cec728842d0e49e

Changing bio->bi_sector; to bio->bi_iter.bi_sector; allows the module to
compile.
