You have modules on ... which means you might decide to load a scsi driver as a module. Maybe one that isn't part of the source tree. The scsi_wait_scan module is only 1500 bytes. Apart from a sense of ideological purity (odd in someone who chooses to use nVidia rather than, say, nv or nouveau), this really isn't a problem. -- Intel are signing my paycheques ... these opinions are still mine "Bill, look, we understand that you're interested in selling us this operating system, but compare it to ours. We can't possibly take such a retrograde step." - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
Fw: scsi_wait_scan Kconfig option
Hi all, Please see below. Nick Begin forwarded message: Date: Fri, 7 Dec 2007 19:12:42 + From: Nick Warne <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: scsi_wait_scan Kconfig option Hi all, I am bringing this up again - primarily as I forgot about it after patching my build tree ages ago: http://lkml.org/lkml/2007/10/27/68 Today I built and installed git for the first time and cloned Linus' tree (very trick!). I try not to build a modular kernel, but only have modules ON due to nVidia (sigh). So I was semi-surprised when I saw the scsi_wait_scan module being built again, yet NO WHERE in menuconfig is it present to turn OFF.
