  "message": "[SCSI] iterate over devices individually for /proc/scsi/scsi\n\nOn systems with very large numbers (\u003e 1600 or so) of SCSI devices,\ncat /proc/scsi/scsi ends up failing with -ENOMEM. This is due to\nthe show routine simply iterating over all of the devices with\nbus_for_each_dev(), and trying to dump all of them into the buffer\nat the same time. On my test system (using scsi_debug with 4064 devices),\nthe output ends up being ~ 632k, far more than kmalloc will typically allow.\n\nThis patch defines its own seq_file opreations to iterate over the scsi\ndevices.The result is that each show() operation only dumps ~ 180 bytes\ninto the buffer at a time so we don\u0027t run out of memory.\n\nIf the \"Attached devices\" header isn\u0027t required, we can dump the\nsfile-\u003eprivate bit completely.\n\nSigned-off-by: Jeff Mahoney \u003cjeffm@suse.com\u003e\nSigned-off-by: James Bottomley \u003cJames.Bottomley@suse.de\u003e\n",
