[PATCH 16/30] blk_end_request: changing i2o_block (take 4)

From: Kiyoshi Ueda
Date: Tue Dec 11 2007 - 17:48:48 EST


This patch converts i2o_block to use blk_end_request interfaces.
Related 'uptodate' arguments are converted to 'error'.

As a result, the interface of internal function, i2o_block_end_request(),
is changed.
