Subject: [PATCH AUTOSEL 5.10 26/41] nvmet: set right status on error in id-ns handler
Date: Fri, 29 Jan 2021 10:36:57 -0500 [thread overview]
Message-ID: <20210129153713.1592185-26-sashal@kernel.org> (raw)
In-Reply-To: <20210129153713.1592185-1-sashal@kernel.org>
From: Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com>
[ Upstream commit bffcd507780ea614b5543c66f2e37ce0d55cd449 ]
The function nvmet_execute_identify_ns() doesn't set the status if call
to nvmet_find_namespace() fails. In that case we set the status of the
request to the value return by the nvmet_copy_sgl().
Set the status to NVME_SC_INVALID_NS and adjust the code such that
request will have the right status on nvmet_find_namespace() failure.
Without this patch :-
