  "message": "[S390] dasd: improve error recovery for internal I/O\n\nMost of the error conditions reported by a FICON storage server\nindicate situations which can be recovered. Sometimes the host just\nneeds to retry an I/O request, but sometimes the recovery\nis more complex and requires the device driver to wait, choose\na different path, etc.\n\nThe DASD device driver has a fully featured error recovery\nfor normal block layer I/O, but not for internal I/O request which\nare for example used during the device bring up.\nThis can lead to situations where the IPL of a system fails because\nDASD devices are not properly recognized.\nThis patch will extend the internal I/O handling to use the existing\nerror recovery procedures.\n\nSigned-off-by: Stefan Weinhuber \u003cwein@de.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n",
