Petersen" , linux-ide@vger.kernel.org Cc: Bart Van Assche Subject: [PATCH] scsi: fix scsi device attributes registration Date: Thu, 11 Nov 2021 17:45:51 +0900 Message-Id: <20211111084551.446548-1-damien.lemoal@opensource.wdc.com> X-Mailer: git-send-email 2.31.1 MIME-Version: 1.0 Content-Transfer-Encoding: quoted-printable Precedence: bulk List-ID: X-Mailing-List: linux-scsi@vger.kernel.org Since the sdev_gendev device of a scsi device defines its attributes using scsi_sdev_attr_groups as the groups field value of its device type, the execution of device_add() in scsi_sysfs_add_sdev() register with sysfs only the attributes defined using scsi_sdev_attr_groups. As a results, the attributes defined by an LLD using the scsi host sdev_groups attribute groups are never registered with sysfs and not visible to the users. Fix this problem by removing scsi_sdev_attr_groups and manually setting the groups field of a scsi device sdev_gendev to point to the scsi device gendev_attr_groups. As the first entry of this array of attribute groups is scsi_sdev_attr_group, using gendev_attr_groups as the gendev groups result in all defined attributes to be created in sysfs when device_add() is called.
