[ Upstream commit b290df06811852d4cc36f4b8a2a30c2063197a74 ] Function ll_rw_block was removed in commit79f5978420("fs/buffer: remove ll_rw_block() helper"). There is no unified function to sumbit read or write buffer in block layer for now. Consider similar sematics, we can choose submit_bh() to replace ll_rw_block() as predefined crash point. In submit_bh(), it also takes read or write flag as the first argument and invoke submit_bio() to submit I/O request to block layer.

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.
