From 598fa4b775d064d4656132c78d9a312eb1d2f91f Mon Sep 17 00:00:00 2001 From: James Bottomley Date: Wed, 17 Jun 2009 15:01:58 -0400 Subject: enhance device info matching for multiple tables The current scsi_devinfo.c matching routines use a single table for the global blacklist. However, we're developing a need to blacklist from specific transports too (notably some tape drives using SPI which don't respond well to high speed protocols). Instead of developing separate blacklist matching for each transport class needing it, enhance the current list matching to permit multiple lists.
