_submit_bh() allowed submitting a buffer_head for I/O using custom
bio_flags. It used to be used by jbd to set BIO_SNAP_STABLE, introduced
by commit 7136851117 ("mm: make snapshotting pages for stable writes a
per-bio operation"). However, the code and flag has since been removed
and no _submit_bh() users remain.
These days, bio_flags are mostly used internally by the block layer to
track the state of bio's. As such, it doesn't really make sense for
filesystems to use them instead of op_flags when wanting special
behavior for block requests.
Therefore, remove _submit_bh() and trim the bio_flags argument from
submit_bh_wbc().

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
