Subject: [PATCH v5 15/25] rnbd: private headers with rnbd protocol structs and helpers
Date: Fri, 20 Dec 2019 16:50:59 +0100
Message-ID: <20191220155109.8959-16-jinpuwang@gmail.com> (raw)
In-Reply-To: <20191220155109.8959-1-jinpuwang@gmail.com>

From: Jack Wang <jinpu.wang@cloud.ionos.com>

These are common private headers with rnbd protocol structures,
logging, sysfs and other helper functions, which are used on
both client and server sides.
