Instead of calling vfs_getattr() use i_size_read() to read the size of file so we can read the size of not only file type but also block type with one call. This is needed to implement buffered_io support for the NVMeOF block device backend. We also change return type of function nvmet_file_ns_revalidate() from int to void, since this function does not return any meaning value.

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.
