[ Upstream commit 56495f295d8e021f77d065b890fc0100e3f9f6d8 ] The megaraid_sas driver supports single LUN for RAID devices. That is LUN 0. All other LUNs are unsupported. When a device scan on a logical target with invalid LUN number is invoked through sysfs, that target ends up getting removed. Add LUN ID validation in the slave destroy function to avoid the target deletion.

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.
