From 659a0e3cda2f5561abe45ccc10afc41014d1a331 Mon Sep 17 00:00:00 2001
Message-Id: <659a0e3cda2f5561abe45ccc10afc41014d1a331@dist-git>
From: Peter Krempa <pkrempa@redhat.com>

Subject: [PATCH] qemu: command: Handle FD passing commandline via
qemuBuildBlockStorageSourceAttachDataCommandline
Copy the pointer to qemuFDPass into struct qemuBlockStorageSourceAttachData
so that it can be used from qemuBuildBlockStorageSourceAttachDataCommandline
rather than looping again in qemuBuildDiskSourceCommandLineFDs.
Signed-off-by: Peter Krempa <pkrempa@redhat.com>

(cherry picked from commit 65f14232fb031b57fad085a2e8792da87c97173f)
