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

[Antony Messerli]

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.
