It's silly to call xfs_setsize_buftarg from xfs_alloc_buftarg with the block device LBA size because we don't need to ask the block layer to validate a geometry number that it provided us. Instead, set the preliminary bt_meta_sector* fields to the LBA size in preparation for reading the primary super. However, we still want to flush and invalidate the pagecache for all three block devices before we start reading metadata from those devices, so call sync_blockdev() per bdev in xfs_alloc_buftarg(). This will enable a subsequent patch to validate hw atomic write geometry against the filesystem geometry. Signed-off-by: Darrick J.

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.
