James Bottomley 529244bd1a scsi: enclosure: Fix stale device oops with hot replug
Doing an add/remove/add on a SCSI device in an enclosure leads to an oops
caused by poisoned values in the enclosure device list pointers.  The
reason is because we are keeping the enclosure device across the enclosed
device add/remove/add but the current code is doing a
device_add/device_del/device_add on it.  This is the wrong thing to do in
sysfs, so fix it by not doing a device_del on the enclosure device simply
because of a hot remove of the drive in the slot.

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.
