esp_scsi: fix reset cleanup spinlock recursion

2007-12-14T17:51:01Z

patch 522939d45c293388e6a360210905f9230298df16 in mainline. The esp_reset_cleanup() function is called with the host lock held and invokes starget_for_each_device() which wants to take it too. Here is a fix along the lines of shost_for_each_device()/__shost_for_each_device() adding a __starget_for_each_device() counterpart which assumes the lock has already been taken. Eventually, I think the driver should get modified so that more work is done as a softirq rather than in the interrupt context, but for now it fixes a bug that causes the spinlock debugger to fire. While at it, it fixes a small number of cosmetic problems with starget_for_each_device() too. Signed-off-by: Maciej W. Rozycki Acked-by: David S.

[SCSI] Remove unused method scsi_device_cancel

[SCSI] zfcp: Report FCP LUN to SCSI midlayer

2007-06-20T02:51:02Z

When reporting SCSI devices to the SCSI midlayer, use the FCP LUN as LUN reported to the SCSI layer. With this approach, zfcp does not have to create unique LUNS, and this code can be removed. Signed-off-by: Christof Schmitt Signed-off-by: Swen Schillig Signed-off-by: James Bottomley

[SCSI] modalias for scsi devices

2007-04-17T22:15:04Z

The following patch adds support for sysfs/uevent modalias attribute for scsi devices (like disks, tapes, cdroms etc), based on whatever current sd.c, sr.c, st.c and osst.c drivers supports. The modalias format is like this: scsi:type-0x04 (for TYPE_WORM, handled by sr.c now). Several comments. o This hexadecimal type value is because all TYPE_XXX constants in include/scsi/scsi.h are given in hex, but __stringify() will not convert them to decimal (so it will NOT be scsi:type-4). Since it does not really matter in which format it is, while both modalias in module and modalias attribute match each other, I descided to go for that 0x%02x format (and added a comment in include/scsi/scsi.h to keep them that way), instead of changing them all to decimal. o There was no .uevent routine for SCSI bus. It might be a good idea to add some more ueven environment variables in there. o osst.c driver handles tapes too, like st.c, but only SOME tapes. With this setup, hotplug scripts (or whatever is used by the user) will try to load both st and osst modules for all SCSI tapes found, because both modules have scsi:type-0x01 alias). It is not harmful, but one extra module is no good either. It is possible to solve this, by exporting more info in modalias attribute, including vendor and device identification strings, so that modalias becomes something like scsi:type-0x12:vendor-Adaptec LTD:device-OnStream Tape Drive and having that, match for all 3 attributes, not only device type. But oh well, vendor and device strings may be large, and they do contain spaces and whatnot. So I left them for now, awaiting for comments first.

[SCSI] sd: implement START/STOP management

2007-03-20T17:06:20Z

Implement SBC START/STOP management. sdev->mange_start_stop is added. When it's set to one, sd STOPs the device on suspend and shutdown and STARTs it on resume. sdev->manage_start_stop defaults is in sdev instead of scsi_disk cdev to allow ->slave_config() override the default configuration but is exported under scsi_disk sysfs node as sdev->allow_restart is. When manage_start_stop is zero (the default value), this patch doesn't introduce any behavior change. Signed-off-by: Tejun Heo Rejections fixed and Signed-off-by: James Bottomley

[SCSI] Make error printing more verbose

2007-03-11T16:17:49Z

This patch enhances SCSI error printing by: - Making use of scsi_print_result() in the completion functions. - Having scmd_printk() output the disk name (when applicable). Signed-off-by: Martin K. Petersen Signed-off-by: James Bottomley

USB Storage: indistinguishable devices with broken and unbroken firmware

2007-02-16T23:32:19Z

there's a USB mass storage device which exists in two version. One reports the correct size and the other does not. Apart from that they are identical and cannot be told apart. Here's a heuristic based on the empirical finding that drives have even sizes. Signed-off-by: Oliver Neukum Acked-by: Alan Stern Acked-by: Matthew Dharm Signed-off-by: Greg Kroah-Hartman

[SCSI] Add ability to scan scsi busses asynchronously

2006-10-11T18:44:25Z

Since it often takes around 20-30 seconds to scan a scsi bus, it's highly advantageous to do this in parallel with other things. The bulk of this patch is ensuring that devices don't change numbering, and that all devices are discovered prior to trying to start init. For those who build SCSI as modules, there's a new scsi_wait_scan module that will ensure all bus scans are finished. This patch only handles drivers which call scsi_scan_host. Fibre Channel, SAS, SATA, USB and Firewire all need additional work. Signed-off-by: Matthew Wilcox Signed-off-by: James Bottomley

[PATCH] scsi: device_reprobe() can fail
