Subject: [RFC PATCH 14/18] rnbd-clt: use init disk helper
Date: Tue, 4 Oct 2022 22:00:23 -0700 [thread overview]
Message-ID: <20221005050027.39591-15-kch@nvidia.com> (raw)
In-Reply-To: <20221005050027.39591-1-kch@nvidia.com>
Add and use the helper to initialize the common fields of struct gendisk
such as major, first_minor, minors, disk_name, private_data, and ops.
This initialization is spread all over the block drivers. This avoids
code repetation of inialization code of gendisk in current block drivers
and any future ones.
