Subject: [PATCH v2 5/5] virtio: Revert "virtio: find_vqs() add arg sizes"
Date: Mon, 15 Aug 2022 17:53:50 -0400 [thread overview]
Message-ID: <20220815215251.154451-8-mst@redhat.com> (raw)
In-Reply-To: <20220815215251.154451-1-mst@redhat.com>
This reverts commit a10fba0377145fccefea4dc4dd5915b7ed87e546: the
proposed API isn't supported on all transports but no
effort was made to address this.
It might not be hard to fix if we want to: maybe just
rename size to size_hint and make sure legacy
transports ignore the hint.
But it's not sure what the benefit is in any case, so
let's drop it.
Fixes: a10fba037714 ("virtio: find_vqs() add arg sizes")
