Subject: [PATCH AUTOSEL 5.10 12/45] scsi: scsi_debug: Fix memleak in scsi_debug_init()
Date: Tue, 19 Jan 2021 20:25:29 -0500 [thread overview]
Message-ID: <20210120012602.769683-12-sashal@kernel.org> (raw)
In-Reply-To: <20210120012602.769683-1-sashal@kernel.org>
From: Dinghao Liu <dinghao.liu@zju.edu.cn>
[ Upstream commit 3b01d7ea4dae907d34fa0eeb3f17bacd714c6d0c ]
When sdeb_zbc_model does not match BLK_ZONED_NONE, BLK_ZONED_HA or
BLK_ZONED_HM, we should free sdebug_q_arr to prevent memleak. Also there is
no need to execute sdebug_erase_store() on failure of sdeb_zbc_model_str().
