[Qemu-devel] [PATCH v6 04/15] iotests: Move _filter_nbd into common.filter

[Max Reitz <mreitz@redhat.com>]

_filter_nbd can be useful for other NBD tests, too, therefore it should
reside in common.filter, and it should support URLs of the "nbd://"
format and export names.

The NBD log lines ("/your/source/dir/nbd.c:function():line: error")
should not be converted to empty lines but removed altogether.

Signed-off-by: Max Reitz <mreitz@redhat.com>
