commit4a067cf823upstream. Up to 4.12, __scsi_error_from_host_byte() would reset the host byte to DID_OK for various cases including DID_NEXUS_FAILURE. Commit2a842acab1("block: introduce new block status code type") replaced this function with scsi_result_to_blk_status() and removed the host-byte resetting code for the DID_NEXUS_FAILURE case. As the line set_host_byte(cmd, DID_OK) was preserved for the other cases, I suppose this was an editing mistake. The fact that the host byte remains set after 4.13 is causing problems with the sg_persist tool, which now returns success rather then exit status 24 when a RESERVATION CONFLICT error is encountered.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
