On Fujitsu ETERNUS systems, sense code ABORTED COMMAND with ASC/Q C1/01 is used to indicate temporary condition where the storage-internal path to a target is switched from one controller to another. SCSI commands that return with this error code must be retried unconditionally (i.e. without the "maybe_retry" logic in scsi_decide_disposition); otherwise dm-multipath might initiate a failover from a healthy path e.g. for REQ_FAILFAST_DEV commands. Introduce a new blist flag for this case. [mkp: applied by hand] Signed-off-by: Martin Wilck <mwilck@suse.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
