From 56f2a8016e0ab54de8daaac3df4712cad0fcef2e Mon Sep 17 00:00:00 2001 From: "Martin K. Petersen" Date: Wed, 24 Apr 2013 21:19:47 -0400 Subject: [SCSI] Workaround for disks that report bad optimal transfer length Not all disks fill out the VPD pages correctly. Add a blacklist flag that allows us ignore the SBC-3 VPD pages for a given device. The BLIST_SKIP_VPD_PAGES flag triggers our existing skip_vpd_pages scsi_device parameter to bypass VPD scanning. Also blacklist the offending Seagate drive model. Reported-by: Mike Snitzer Signed-off-by: Martin K.
