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. Even if I hand edit .config, make puts it back again...
.config

# CONFIG_SCSI_NETLINK is not set
# CONFIG_SCSI_PROC_FS is not set
#

# CONFIG_CHR_DEV_OSST is not set
# CONFIG_BLK_DEV_SR is not set
# CONFIG_CHR_DEV_SG is not set
# CONFIG_CHR_DEV_SCH is not set
#
# Some SCSI devices (e.g. CD jukebox) support multiple LUNs
#
# CONFIG_SCSI_MULTI_LUN is not set
# CONFIG_SCSI_CONSTANTS is not set
# CONFIG_SCSI_LOGGING is not set
# CONFIG_SCSI_SCAN_ASYNC is not set
CONFIG_SCSI_WAIT_SCAN=m
I have attached my patch again :-)
