Linux kernel stable tree
36ebf1e2aa
If a driver returns: - DID_TARGET_FAILURE - DID_NEXUS_FAILURE - DID_ALLOC_FAILURE - DID_MEDIUM_ERROR we hit a couple bugs: 1. The SCSI error handler runs because scsi_decide_disposition() has no case statements for them and we return FAILED. 2. For SG IO the userspace app gets a success status instead of failed, because scsi_result_to_blk_status() clears those errors. This patch adds a new internal error code byte for use by the SCSI midlayer. This will be used instead of the above error codes, so we don't have to play that clearing the host code game in scsi_result_to_blk_status() and drivers cannot accidentally use them. A subsequent commit will then remove the internal users of the above codes and convert us to use the new ones.

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.
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.
