Subject: [PATCH AUTOSEL 6.7 35/44] nvmet-fc: free queue and assoc directly
Date: Wed,  7 Feb 2024 16:21:02 -0500	[thread overview]
Message-ID: <20240207212142.1399-35-sashal@kernel.org> (raw)
In-Reply-To: <20240207212142.1399-1-sashal@kernel.org>

From: Daniel Wagner <dwagner@suse.de>

[ Upstream commit c5e27b1a779ec25779d04c3af65aebaee6bd4304 ]

Neither struct nvmet_fc_tgt_queue nor struct nvmet_fc_tgt_assoc are data
structure which are used in a RCU context. So there is no reason to
delay the free operation.
