How about just killing transport_generic_process_write and calling
transport_execute_tasks directly?

Thanks for reviewing the set. I'm going to wait a day or two to see if
more comments come in, then I'll repost. I'm inclined to agree with all
your comments, except I'll probably save the change mentioned above for
a follow-on patchset, unless it's fixed in the meantime.
Thanks again -- Regards -- Andy

Since sectors is not modified, it's more straightforward to do this.

Previously, some control CDBs did not allocate memory in pages for their
data buffer, but just did a kmalloc. This patch makes all cdbs allocate
pages.
This has the benefit of streamlining some paths that had to behave
differently when we used two allocation methods. The downside is that
all accesses to the data buffer need to kmap it before use, and need to
handle data in page-sized chunks if more than a page is needed for a given
command's data buffer.

It would be good to use goto unwinding here and in all other control
CDB handlers that may return errors.

The rd_dr ramdisk implementation is closely tied with struct se_mem.
Disable it before removing struct se_mem. I'm not sure if we want to
fix up and re-enable it, or maybe just decide we can live without it and
remove it entirely.

Both backstores and fabrics use arrays of struct scatterlist to describe
data buffers. However TCM used struct se_mems, basically a linked list
of scatterlist entries. We are able to simplify the code by eliminating
this intermediate data structure and just using struct scatterlist[]
throughout.

Why bother going through the loops if we're not going to free
anything? Might be worth to split this into a function doin the
clearing, which only gets condtionally called, and one zeroing out
the members, that also conditionally calls the low-level helper.

This code pretty much is exactly the same as allocation in
iscsit_alloc_buffs. If we can't switch iscsi to use internal buffers
directly we should at least export this helper so it can use it.
That also means killing the superflous t_mem_sg/t_mem_sg_nents members
in favour of t_data/t_data_nents.

What about making transport_allocate_control_task return the expected
value directly?

transport_map_control_cmd_to_task might have called ->cdb_none
before. While I'd love to kill that method I haven't seen any work
towards actually making that happen. So for now I suspect you'll
still need the conditionally call to ->cdb_none.

Yeah I think iscsi can go back to relying on the core to allocate. I
know it's a little weird to change it to self-allocation and then back,
but what the move to self-allocation *really* was about was getting
se_mem out of iscsi. Now that core no longer has se_mem, and allocating
data buffs doesn't involve task switches, having core allocate data
buffs sounds good again.

pr_debug and dynamic debug can give us the flexibility to choose
debugprints in a more standard way than these macros.
Since these debug statements were seldom enabled, there was some bitrot
in their parameters, so those are also corrected.
Use pr_err etc. macros instead of printk(KERN_ERR..).

pr_debug and dynamic debug messages are cool, we don't need specialized
debug infrastructure.
Use pr_err etc. instead of printk(KERN_ERR...).

To: target-devel; +Cc: linux-scsi
This should have the effect of quieting dmesg output when there are no
issues, and yet still allow these messages to be enabled during a debugging
session if needs be.
Replaced all printk(KERN_ERR) with pr_err()
Replaced all printk(KERN_INFO) with pr_debug()
Replaced all uses of TRACE() with pr_debug()
Moved PRINT_BUFF macro to iscsi_target_util.c, only place it's used
Remove iscsi debug config option

The definition of what's a data and what's a control CDB is not
totally clear, but both of these set t_task_lba, so I'm inclined
to call them data CDBs.

Currently DATA cdbs are those that get passes through to the
backend (except for pscsi which gets all of them). As the backends
can't handle WRITE_SAME this patch is incorrect.
I have a nice prototype to kill that whole DATA vs CONTROL flag thing,
which will be much nicer after your series. Once the guts of your
patches hit the tree I'll resubmit them.

Ah yes that makes sense, I'll delete this patch.

Sounds really good. I was pondering if that was possible.

According to sbc3r27, WRITE SAME with sectors=0 either writes to the
end of the lun, or returns an error, depending on if WSNZ was set to 0 or
1 in the block limits VPD (0xB0). This patch sets that bit, and
returns the error. Previously we used the block size, I don't know why,
but it seems wrong.

Due to all cdbs' data buffers being referenced by scatterlists, buffers
of more than a page are not contiguous. Instead of handling this in all
control command handlers, we may be able to get away with just limiting
control cdb data buffers to one page. The only control CDBs we handle that
have potentially large data buffers are REPORT LUNS and UNMAP, so if we
didn't want to live with this limitation, they would need to be modified
to walk the pages in the data buffer's sgl.

I think this should be moved earlier in the series, that is before
making all control CDBs use SG lists.

Instead of converting rd_dr to be se_mem-free, maybe we should just
remove it. Do we really need *two* private ramdisk implementations,
especially when the kernel already has its own ramdisk code, that we
could access via the iblock backstore?
This also lets us remove hooks like do_se_mem_map, that are in the common
path but only implemented by rd_dr.

I always hated the hooks the direct ramdisk code had to the core code,
so I'm absolutely in favour of it. The indirect ramdisk currently is
used for things like the virtual lun0 handling, which requires it to
be just there instead of setting up a block device. I think keeping
the simple internal ramdisk around for that and benchmarking is fine.

This callback was only used by the direct ramdisk driver, which is no
longer present.
