  "message": "[SCSI] Reduce error recovery time by reducing use of TURs\n\nIn error recovery, most scsi error recovery stages will send a TUR command\nfor every bad command when a driver\u0027s error handler reports success.  When\nseveral bad commands to the same device, this results in a device\nbeing probed multiple times.\n\nThis becomes very problematic if the device or connection is in a state\nwhere the device still doesn\u0027t respond to commands even after a recovery\nfunction returns success.  The error handler must wait for the test\ncommands to time out.  The time waiting for the redundant commands can\ndrastically lengthen error recovery.\n\nThis patch alters the scsi mid-layer\u0027s error routines to send test commands\nonce per device instead of once per bad command.  This can drastically\nlower error recovery time.\n\n[jejb: fixed up whitespace and formatting]\nSigned-of-by: David Jeffery \u003cdjeffery@redhat.com\u003e\nSigned-off-by: James Bottomley \u003cjbottomley@parallels.com\u003e\n",
