The following two header files have the same file name: include/scsi/scsi.h and drivers/scsi/scsi.h. This is confusing. Remove the latter since the following note was added in drivers/scsi/scsi.h in 2004: "NOTE: this file only contains compatibility glue for old drivers. All these wrappers will be removed sooner or later. For new code please use the interfaces declared in the headers in include/scsi/" Link: https://lore.kernel.org/r/20220218195117.25689-7-bvanassche@acm.org Cc: Christoph Hellwig <hch@lst.de> Cc: Ming Lei <ming.lei@redhat.com> Reviewed-by: Hannes Reinecke <hare@suse.com> Reviewed-by: Himanshu Madhani <himanshu.madhani@oracle.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Bart Van Assche <bvanassche@acm.org> Signed-off-by: Martin K.

* Driver for USB Mass Storage compliant devices
|
|
* Debugging Functions Source Code File
|
|
*
|
|
* Current development and maintenance by:
|
|
* (c) 1999-2002 Matthew Dharm (mdharm-usb@one-eyed-alien.net)
|
|
*
|
|
* Developed with the assistance of:
|
|
* (c) 2002 Alan Stern <stern@rowland.org>
|
|
*
|
|
* Initial work by:
|
|
* (c) 1999 Michael Gee (michael@linuxspecific.com)
|
|
*
|
|
* This driver is based on the 'USB Mass Storage Class' document. This
|
|
* describes in detail the protocol used to communicate with such
|
|
* devices. Clearly, the designers had SCSI and ATAPI commands in
|
|
* mind when they created this document. The commands are all very
|
|
* similar to commands in the SCSI-II and ATAPI specifications.
|
|
*
|
|
* It is important to note that in a number of cases this class
|
|
* exhibits class-specific exemptions from the USB specification.
|
|
* Notably the usage of NAK, STALL and ACK differs from the norm, in
|
|
* that they are used to communicate wait, failed and OK on commands.
|
|
*
|
|
* Also, for certain devices, the interrupt endpoint is used to convey
|
|
* status of a command.
