Using dev_printk to implement shost_printk leads to somewhat lacklustre results: host2: SCSI BUS has been reset scsi2 : sym-2.2.3 By reimplementing shost_printk directly on top of printk, we can get the more pleasing: scsi 0: SCSI BUS has been reset scsi 0: sym-2.2.3 It fits in well with scsi 0:0:1:0: Optical Device MATSHITA PD-1 LF-1000 A105 PQ: 0 ANSI: 2 I'm less sure about the part of this patch which applies to starget_printk. It would be quite awkward to find the scsi_host, print its number, then print the channel and id of the starget. The compromise in this patch is to print: scsi target0:0:1: Beginning Domain Validation which at least doesn't penalise the caller of starget_printk. Maybe we could stash a pointer to the scsi_host directly in scsi_target, or just the scsi_host's number. diff --git a/include/scsi/scsi_host.h b/include/scsi/scsi_host.h index 5b79697..2268aa8 100644 --- a/include/scsi/scsi_host.h +++ b/include/scsi/scsi_host.h @@ -675,7 +675,7 @@ struct Scsi_Host { container_of(d, struct Scsi_Host, shost_classdev) #define shost_printk(prefix, shost, fmt, a...) \ - dev_printk(prefix, &(shost)->shost_gendev, fmt, ##a) + printk(prefix "scsi %d: " fmt, (shost)->host_no , ##a) static inline void *shost_priv(struct Scsi_Host *shost) { diff --git a/include/scsi/scsi_device.h b/include/scsi/scsi_device.h index d5057bc..4437b60 100644 --- a/include/scsi/scsi_device.h +++ b/include/scsi/scsi_device.h @@ -202,7 +202,7 @@ static inline struct scsi_target *scsi_target(struct scsi_device *sdev) to_scsi_target(class_dev->dev) #define starget_printk(prefix, starget, fmt, a...) \ - dev_printk(prefix, &(starget)->dev, fmt, ##a) + printk(prefix "scsi %s: " fmt, (starget)->dev.bus_id , ##a) extern struct scsi_device *__scsi_add_device(struct Scsi_Host *, uint, uint, uint, void *hostdata); diff --git a/drivers/scsi/hosts.c b/drivers/scsi/hosts.c index adc9559..173de6d 100644 --- a/drivers/scsi/hosts.c +++ b/drivers/scsi/hosts.c @@ -194,7 +194,7 @@ int scsi_add_host(struct Scsi_Host *shost, struct device *dev) struct scsi_host_template *sht = shost->hostt; int error = -EINVAL; - printk(KERN_INFO "scsi%d : %s\n", shost->host_no, + shost_printk(KERN_INFO, shost, "%s\n", sht->info ? sht->info(shost) : sht->name); if (!shost->can_queue) { -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours.
