Message-Id: <5278c00147b0ac777d5ddd73062d0c6146da4908@dist-git>

Subject: [PATCH] qemu: blockjob: Store 'jobflags' with block job data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Add a variable which will store the contents of the 'flags' variable as
passed in by the individual block jobs. Since the flags may influence
behaviour of the jobs it's important to preserve them to the
finalization steps.
