David Kozub 2b18febc8c block: sed-opal: fix IOC_OPAL_ENABLE_DISABLE_MBR 
[ Upstream commit 78bf47353b ]

The implementation of IOC_OPAL_ENABLE_DISABLE_MBR handled the value
opal_mbr_data.enable_disable incorrectly: enable_disable is expected
to be one of OPAL_MBR_ENABLE(0) or OPAL_MBR_DISABLE(1). enable_disable
was passed directly to set_mbr_done and set_mbr_enable_disable where
is was interpreted as either OPAL_TRUE(1) or OPAL_FALSE(0). The end
result was that calling IOC_OPAL_ENABLE_DISABLE_MBR with OPAL_MBR_ENABLE
actually disabled the shadow MBR and vice versa.

This patch adds correct conversion from OPAL_MBR_DISABLE/ENABLE to
OPAL_FALSE/TRUE. The change affects existing programs using
IOC_OPAL_ENABLE_DISABLE_MBR but this is typically used only once when
setting up an Opal drive.

README 

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.
