Subject: [PATCH 06/14] block/blkio: use blkio_set_int("fd") to check fd

|
|
|
|
Setting the `fd` property fails with virtio-blk-* libblkio drivers
|
|
that do not support fd passing since
|
|
https://gitlab.com/libblkio/libblkio/-/merge_requests/208.
|
|
|
|
Getting the `fd` property, on the other hand, always succeeds for
|
|
virtio-blk-* libblkio drivers even when they don't support fd passing.
|
|
|
|
This patch switches to setting the `fd` property because it is a
|
|
better mechanism for probing fd passing support than getting the `fd`
|
|
property.
