Subject: [PATCH v2 08/26] nvmet-fc: Update target for common definitions for LS handling
Date: Tue, 31 Mar 2020 09:49:53 -0700	[thread overview]
Message-ID: <20200331165011.15819-9-jsmart2021@gmail.com> (raw)
In-Reply-To: <20200331165011.15819-1-jsmart2021@gmail.com>

Given that both host and target now generate and receive LS's create
a single table definition for LS names. Each tranport half will have
a local version of the table.

Convert the target side transport to use the new common Create
Association LS validation routine.

v2:
  Split original patch into two patches: a host-side patch (with header
  update) and a target-side patch.
