James or anyone else: The purpose of the scsi_wait_scan module is to provide a method for initramfs images to wait until all the SCSI drives available at boot-up have been discovered and probed, so that the drive containing the root filesystem will be available when the time comes to mount it. Now, in include/scsi/scsi_scan.h, the declaration of scsi_complete_async_scans() depends on CONFIG_SCSI. If the SCSI core is built as a module, scsi_complete_async_scans() is defined as an empty inline routine. This doesn't seem to make any sense. The drive containing the root filesystem needs to be available for mounting regardless of whether scsi_mod is built into the kernel or is loaded as a module within an initramfs image. In short, is there any reason not to remove the "#ifdef CONFIG_SCSI" from include/scsi/scsi_scan.h? My reason for asking is because I need to fix a bug in scsi_pm.c, and the fix involves calling scsi_complete_async_scans(). This has to happen even when CONFIG_SCSI isn't defined, so I'd like to change the header file. If necessary, I can put the call in scsi_wait_scan.c inside a "#ifdef CONFIG_SCSI" block.
