Re: [PATCH 15/17] qemuMigrationSrcNBDCopyCancel: Use qemuBlockStorageSourceAttachRollback to detach migration NBD blockdevs

Rewrite the code to use the common tooling for removing blockdevs instead of the ad-hoc qemuBlockStorageSourceDetachOneBlockdev helper. Use of the common infrastructure will properly handle cases when the raw driver is ommited from the block graph. Since the TLS data object is shared for all migration QMP commands and objects we need to strip it's alias from the definition of the storage

source before attempting to detach it. Signed-off-by: Peter Krempa <pkrempa(a)redhat.com&gt; --- src/qemu/qemu_migration.c | 18 ++++++++++++++++-- 1 file changed, 16 insertions(+), 2 deletions(-)
