From
Subject[PATCH 0/4] towards an async_tx update for 2.6.25
Date
Prompted by Yuri's RAID6 acceleration implementation [1], and Haavard's
DMA-slave interface [2], this series cleans up the async_tx api and prepares
it for these new features. The most invasive change is the removal of
the tx_set_src and tx_set_dest methods in patch 2/4, drivers now receive
all necessary operation information at 'prep' time.

Still on the to do list:
* Pull the mpc85xx driver from -mm and integrate these api changes
* Apply Haavard's dma-test-client [3]. Look into extending it for
other operations and async_tx channel switching testing
* Teach async_tx about drivers that do not support channel switching

This series is based on 2.6.24-rc6.

Dan Williams (4):
async_tx: kill ASYNC_TX_ASSUME_COHERENT
async_tx: kill tx_set_src and tx_set_dest methods
async_tx: replace 'int_en' with operation preparation flags
async_tx: allow architecture specific async_tx_find_channel implementations
