Subject: [PATCH 0/9] dasd: implement block timeout
Date: Tue, 29 Jan 2013 08:11:52 +0100 [thread overview]
Message-ID: <1359443521-24670-1-git-send-email-hare@suse.de> (raw)
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
