From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>
Greetings folks,
This patch series pushes the remaining SPC-3 control path CDB emualation for
INQUIRY, READ_CAPACITY_*, UNMAP and WRITE_SAME w/ UNMAP=1, and SYNCHRONIZE_CACHE_*
subsystem plugin handling into generic TCM code.
It follows Christoph's recommendation to pick off the non SCF_SCSI_DATA_SG_IO_CDB
struct se_tasks before hitting struct se_subsysem_api->do_task(), and removal of
struct se_subsystem_api_cdb initially added in commit 3712c6da407.
So far this has been tested with TCM/IBLOCK and TCM/FILEIO subsystem plugins on
v2.6.36-rc7 x86 HVM with sg_inquiry, sg_readcap, sg_unmap, sg_write_same -[ST] -U,
and sg_sync.
Thanks again go out to hch for pushing for IBLOCK and FILEIO to become drivers/scsi
independent and save yet another ~80 LOC from the v4.0 tree! Thanks Christoph!!!
