Subject: [PATCH 5.12 30/45] scsi: target: tcmu: Return from tcmu_handle_completions() if cmd_id not found
Date: Thu, 20 May 2021 11:22:18 +0200 [thread overview]
Message-ID: <20210520092054.502247755@linuxfoundation.org> (raw)
In-Reply-To: <20210520092053.516042993@linuxfoundation.org>
From: Bodo Stroesser <bostroesser@gmail.com>
[ Upstream commit 9814b55cde0588b6d9bc496cee43f87316cbc6f1 ]
If tcmu_handle_completions() finds an invalid cmd_id while looping over cmd
responses from userspace it sets TCMU_DEV_BIT_BROKEN and breaks the
loop. This means that it does further handling for the tcmu device.
Skip that handling by replacing 'break' with 'return'.
Additionally change tcmu_handle_completions() from unsigned int to bool,
since the value used in return already is bool.
