Subject: [PATCH 19/19]: tgt: Removal
Because of the conversion of the ibmvstgt driver from tgt to SCST, and because
the ibmvstgt driver was the only user of scsi_tgt, the scsi_tgt kernel module,
the CONFIG_SCSI_TGT, CONFIG_SCSI_SRP_TGT_ATTRS and CONFIG_SCSI_FC_TGT_ATTRS
kbuild variable, the scsi_host_template member variables transfer_response,
supportedmode and active_mode and the constants MODE_UNKNOWN, MODE_INITIATOR
and MODE_TARGET are no longer needed.
Note: this patch applies cleanly on a 2.6.35 kernel tree. The patch tool
however complains about the defconfig changes when trying to apply this patch
on a 2.6.36 kernel tree.
