The async_tx api provides methods for describing a chain of asynchronous
bulk memory transfers/transforms with support for inter-transactional
dependencies. It is implemented as a dmaengine client that smooths over
the details of different hardware offload engine implementations. Code
that is
Prepare the raid5 implementation to use async_tx for running stripe
operations:
* biofill (copy data into request buffers to satisfy a read request)
* compute block (generate a missing block in the cache from the other
blocks)
* prexor (subtract existing data as part of the read-modify-write
Each stripe has three flag variables to reflect the state of operations
(pending, ack, and complete).
-pending: set to request servicing in raid5_run_ops
-ack: set to reflect that raid5_runs_ops has seen this request
-complete: set when the operation is complete and it is ok for handle_stripe5
to
handle_stripe sets STRIPE_OP_PREXOR, STRIPE_OP_BIODRAIN, STRIPE_OP_POSTXOR
to request a write to the stripe cache. raid5_run_ops is triggerred to run
and executes the request outside the stripe lock.
Changelog:
* make the 'rcw' parameter to handle_write_operations5 a simple flag, Neil
Brown
*
handle_stripe sets STRIPE_OP_COMPUTE_BLK to request servicing from
raid5_run_ops. It also sets a flag for the block being computed to let
other parts of handle_stripe submit dependent operations. raid5_run_ops
guarantees that the compute operation completes before any dependent
operation starts.
handle_stripe sets STRIPE_OP_CHECK to request a check operation in
raid5_run_ops. If raid5_run_ops is able to perform the check with a
dma engine the parity will be preserved in memory removing the need to
re-read it from disk, as is necessary in the synchronous case.
'Repair' operations re-use
Use raid5_run_ops to carry out the memory copies for a raid5 read request.

The parity calculation for an expansion operation is the same as the
calculation performed at the end of a write with the caveat that all blocks
in the stripe are scheduled to be written. An expansion operation is
identified as a stripe with the POSTXOR flag set and the BIODRAIN flag not
set.
handle_stripe now only updates the state of stripes. All execution of
operations is moved to raid5_run_ops.

I didn't check whether the patch actually permits us to read kernel
memory. Probably it does. Probably we'd

Duh. I have a couple of pages of may be used uninitialized warnings.

Hi All,
An update of the uClinux (MMU-less) code against 2.6.21.
A lot of cleanups, and a few bug fixes.
Ahead is more changes to finalize platform device support
for the new style ColdFire serial driver, and switching to
the generic irq

Hi Linus,
As you may know, we've been working on a new FireWire stack over on

Any chance you could split this into a few patches and send
upstream? m68knommu has gone quite badly out of sync once again.

Most comments states Cyrix CPUs when they are using the macros. Is anything
with Cyrix 64 bit relevant? Maybe include/asm-x86_64/processor.h is a
simple copy of include/asm-i386/processor.h and nobody delete the unused

Hi!
I mean the SVGA chip-specific code.
Feel free to kill it, anybody using these cards is very unlikely to run
