The patch titled
scsi: fix CONFIG_SCSI_WAIT_SCAN=m
has been removed from the -mm tree. Its filename was
scsi-fix-config_scsi_wait_scan=m.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: scsi: fix CONFIG_SCSI_WAIT_SCAN=m
From: Hugh Dickins <hugh@xxxxxxxxxxx>
CONFIG_MODULES=y
CONFIG_SCSI=y
CONFIG_SCSI_SCAN_ASYNC=y
CONFIG_SCSI_WAIT_SCAN=m
2.6.21-rc5-mm2 VFS panics unable to find my root on /dev/sda2, but boots
okay if I change drivers/scsi/Kconfig to "default y" instead of "default m"
for SCSI_WAIT_SCAN.
Make sure there's a late_initcall to scsi_complete_async_scans when it's
built in, so a monolithic SCSI_SCAN_ASYNC kernel can rely on the scans
being completed before trying to mount root, even if they're slow.

James sayeth "This isn't the right fix ... this has to be invoked last in the
call sequence ... I can't see another way of doing this except yet another
file added as a final component to the link."
