Nilay Shroff e38dad438f nvmet-passthru: clear EUID/NGUID/UUID while using loop target 
When nvme passthru is configured using loop target, the clear_ids
attribute is, by default, set to true. This attribute would ensure that
EUID/NGUID/UUID is cleared for the loop passthru target.

The newer NVMe disk supporting the NVMe spec 1.3 or higher, typically,
implements the support for "Namespace Identification Descriptor list"
command. This command when issued from host returns EUID/NGUID/UUID
assigned to the inquired namespace. Not clearing these values, while
using nvme passthru using loop target, would result in NVMe host driver
rejecting the namespace. This check was implemented in the commit
2079f41ec6 ("nvme: check that EUI/GUID/UUID are globally unique").

The fix implemented in this commit ensure that when host issues ns-id
descriptor list command, the EUID/NGUID/UUID are cleared by passthru
target. In fact, the function nvmet_passthru_override_id_descs() which
clears those unique ids already exits, so we just need to ensure that
ns-id descriptor list command falls through the corretc code path. And
while we're at it, we also combines the three passthru admin command
cases together which shares the same code.

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 reStructuredText 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.
