When CONFIG_NVME_MULTIPATH is set, only the hidden gendisk associated with the per-controller ns is run through revalidate_disk when a rescan is triggered, while the visible blockdev never gets its size (bdev->bd_inode->i_size) updated to reflect any capacity changes that may have occurred. This prevents online resizing of nvme block devices and in extension of any filesystems atop that will are unable to expand while mounted, as userspace relies on the blockdev size for obtaining the disk capacity (via BLKGETSIZE/64 ioctls). Fix this by explicitly revalidating the actual namespace gendisk in addition to the per-controller gendisk, when multipath is enabled.

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.
