Subject: [PATCHv5 for-next 06/19] block/rnbd: Kill rnbd_clt_destroy_default_group
Date: Mon, 19 Apr 2021 09:37:09 +0200
Message-ID: <20210419073722.15351-7-gi-oh.kim@ionos.com> (raw)
In-Reply-To: <20210419073722.15351-1-gi-oh.kim@ionos.com>

From: Guoqing Jiang <guoqing.jiang@cloud.ionos.com>

No need to have it since we can call sysfs_remove_group in the
rnbd_clt_destroy_sysfs_files.

Then rnbd_clt_destroy_sysfs_files is paired with it's counterpart
rnbd_clt_create_sysfs_files.
