Subject: [PATCH 13/30] blk_end_request: changing viodasd (take 4)
Date: Tue, 11 Dec 2007 17:47:14 -0500 (EST) [thread overview]
Message-ID: <20071211.174714.42908160.k-ueda@ct.jp.nec.com> (raw)
This patch converts viodasd to use blk_end_request interfaces.
Related 'uptodate' arguments are converted to 'error'.
As a result, the interface of internal function, viodasd_end_request(),
is changed.
