Subject: [PATCH 01/17] smb: client: introduce DFS_CACHE_TGT_LIST()
Date: Thu, 17 Aug 2023 12:33:59 -0300	[thread overview]
Message-ID: <20230817153416.28083-2-pc@manguebit.com> (raw)
In-Reply-To: <20230817153416.28083-1-pc@manguebit.com>

Add new helper which declares and initialises target list of a DFS
referral rather having to do both separately.

No functional changes.
