From d0a7e574007fd547d72ec693bfa35778623d0738 Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Sun, 14 Aug 2005 17:09:01 -0500 Subject: [SCSI] correct transport class abstraction to work outside SCSI I recently tried to construct a totally generic transport class and found there were certain features missing from the current abstract transport class. Most notable is that you have to hang the data on the class_device but most of the API is framed in terms of the generic device, not the class_device. These changes are two fold - Provide the class_device to all of the setup and configure APIs - Provide and extra API to take the device and the attribute class and return the corresponding class_device Signed-off-by: James Bottomley --- drivers/scsi/scsi_transport_fc.c | 6 ++++-- drivers/scsi/scsi_transport_spi.c | 11 ++++++++--- 2 files changed, 12 insertions(+), 5 deletions(-) (limited to 'drivers/scsi') diff --git a/drivers/scsi/scsi_transport_fc.c b/drivers/scsi/scsi_transport_fc.c index 35d1c1e8e34..96243c7fe11 100644 --- a/drivers/scsi/scsi_transport_fc.c +++ b/drivers/scsi/scsi_transport_fc.c @@ -252,7 +252,8 @@ struct fc_internal { #define to_fc_internal(tmpl) container_of(tmpl, struct fc_internal, t) -static int fc_target_setup(struct device *dev) +static int fc_target_setup(struct transport_container *tc, struct device *dev, + struct class_device *cdev) { struct scsi_target *starget = to_scsi_target(dev); struct fc_rport *rport = starget_to_rport(starget); @@ -281,7 +282,8 @@ static DECLARE_TRANSPORT_CLASS(fc_transport_class, NULL, NULL); -static int fc_host_setup(struct device *dev) +static int fc_host_setup(struct transport_container *tc, struct device *dev, + struct class_device *cdev) { struct Scsi_Host *shost = dev_to_shost(dev); diff --git a/drivers/scsi/scsi_transport_spi.c b/drivers/scsi/scsi_transport_spi.c index 02134fce217..89f6b7feb9c 100644 --- a/drivers/scsi/scsi_transport_spi.c +++ b/drivers/scsi/scsi_transport_spi.c @@ -162,7 +162,8 @@ static inline enum spi_signal_type spi_signal_to_value(const char *name) return SPI_SIGNAL_UNKNOWN; } -static int spi_host_setup(struct device *dev) +static int spi_host_setup(struct transport_container *tc, struct device *dev, + struct class_device *cdev) { struct Scsi_Host *shost = dev_to_shost(dev); @@ -196,7 +197,9 @@ static int spi_host_match(struct attribute_container *cont, return &i->t.host_attrs.ac == cont; } -static int spi_device_configure(struct device *dev) +static int spi_device_configure(struct transport_container *tc, + struct device *dev, + struct class_device *cdev) { struct scsi_device *sdev = to_scsi_device(dev); struct scsi_target *starget = sdev->sdev_target; @@ -214,7 +217,9 @@ static int spi_device_configure(struct device *dev) return 0; } -static int spi_setup_transport_attrs(struct device *dev) +static int spi_setup_transport_attrs(struct transport_container *tc, + struct device *dev, + struct class_device *cdev) { struct scsi_target *starget = to_scsi_target(dev); -- cgit v1.2.3
