Gibbs" , bferjul@emc.com, jkrasner@emc.com, conway_heather@emc.com, linux-scsi@vger.kernel.org I'd rather have to add a list entry for one of a few dozen storage array vendors then get hundreds bug reports from noname USB block devices that blew up when we sent REPORT_LUNS. Considering a lot of them blow up if you ask for more than a 36 byte INQUIRY response, I think REPORT_LUNS should be special cased in the blacklist. I haven't been tracking 2.5, but I knew there were plans to push push the scanning code and the blacklist stuff into a userspace scsid. Did this make it?
