Subject: [PATCH v2 06/10] NFSD add COPY_NOTIFY operation
Date: Fri, 30 Nov 2018 15:03:44 -0500
Message-ID: <20181130200348.59524-7-olga.kornievskaia@gmail.com> (raw)
In-Reply-To: <20181130200348.59524-1-olga.kornievskaia@gmail.com>

Introducing the COPY_NOTIFY operation.

Create a new unique stateid that will keep track of the copy
state and the upcoming READs that will use that stateid. Keep
it in the list associated with parent stateid.

Return single netaddr to advertise to the copy.
