Subject: [Qemu-devel] [PULL 14/14] block/null: Expose read-zeroes option in QAPI schema
Date: Tue, 18 Jun 2019 17:23:18 +0200 [thread overview]
Message-ID: <20190618152318.24953-15-kwolf@redhat.com> (raw)
In-Reply-To: <20190618152318.24953-1-kwolf@redhat.com>
Commit cd219eb1e55 added the read-zeroes option for the null-co and
null-aio block driver, but forgot to add them to the QAPI schema.
Therefore, this option wasn't available in -blockdev and blockdev-add
until now.
Add the missing option in the schema to make it available there, too.
