Subject: [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.

Hannes Reinecke (9):
  dasd: Clarify comment
  dasd: make number of retries configurable
  dasd: process all requests in the device tasklet
  dasd: Implement block timeout handling
  dasd: Reduce amount of messages for specific errors
  dasd: detailed I/O errors
  block: check for timeout function in blk_rq_timed_out()
  dasd: Add 'timeout' attribute
  dasd: Fail all requests when DASD_FLAG_ABORTIO is set
