[Pkg-xen-devel] Bug#742515: blktap-dkms: blktapblktap kernel module failed to build

[Antony Messerli]

Package: blktap-dkms
Version: 2.0.93-0.1
Severity: serious
Justification: fails to build from source (but built successfully in the past)

blktap fails to build on kernel 3.13 and probably older kernels as well.  According to this bug: https://bugs.launchpad.net/ubuntu/+source/blktap-dkms/+bug/1245009 VM_RESERVED is deprecated as of 3.7.  Building with the patch described in that bug allows for blktap to build properly.
