The patched code is used to get chunks number, should use round-up div to replace current sector_div. The same code is in md_bitmap_resize(): ``` chunks = DIV_ROUND_UP_SECTOR_T(blocks, 1 << chunkshift); ``` Signed-off-by: Zhao Heming <heming.zhao@suse.com> Signed-off-by: Song Liu <songliubraving@fb.com>
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.
