[PATCH 0/9] dasd: implement block timeout

This patch series implements a block timeout handler for
DASDs. The main impetus was to allow for a fixed upper
timeout value after which a request is aborted.
This is required eg when implementing a host-based
mirroring system where otherwise the entire mirror
would stall under certain circumstances.

Please apply.
