Anton Eidelman ec49f3f7f6 nvme-multipath: fix ANA state updates when a namespace is not present
[ Upstream commit 79f528afa93918519574773ea49a444c104bc1bd ]

nvme_update_ana_state() has a deficiency that results in a failure to
properly update the ana state for a namespace in the following case:

  NSIDs in ctrl->namespaces:	1, 3,    4
  NSIDs in desc->nsids:		1, 2, 3, 4

Loop iteration 0:
    ns index = 0, n = 0, ns->head->ns_id = 1, nsid = 1, MATCH.
Loop iteration 1:
    ns index = 1, n = 1, ns->head->ns_id = 3, nsid = 2, NO MATCH.
Loop iteration 2:
    ns index = 2, n = 2, ns->head->ns_id = 4, nsid = 4, MATCH.

Where the update to the ANA state of NSID 3 is missed.  To fix this
increment n and retry the update with the same ns when ns->head->ns_id is
higher than nsid,

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.

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.
