From 0f64e078139109d1902e5b1274c23cec9a9ad12e Mon Sep 17 00:00:00 2001 From: Matthew Dharm Date: Thu, 28 Jul 2005 14:43:08 -0700 Subject: [PATCH] USB Storage: remove dependency on SCSI-provided serial/tag number This patch started life as as531 from Alan Stern. It has been rediffed against the latest tree. The SCSI people have deprecated the use of scsi_cmnd.serial_number for anything other than printk. Worse than that, the SCSI core doesn't always increment the number (when the error handler is running, for example). So this patch creates a locally-stored value for use in bulk-only tags. The net result is a simplification, since we no longer have to save & restore the serial_number value while autosensing.
