Before this patch, the implementation is hacky and hard to understand: 1) md_seq_start set pos to 1; 2) md_seq_show found pos is 1, then print Personalities; 3) md_seq_next found pos is 1, then it update pos to the first mddev; 4) md_seq_show found pos is not 1 or 2, show mddev; 5) md_seq_next found pos is not 1 or 2, update pos to next mddev; 6) loop 4-5 until the last mddev, then md_seq_next update pos to 2; 7) md_seq_show found pos is 2, then print unused devices; 8) md_seq_next found pos is 2, stop; This patch remove the magic value and use seq_list_start/next/stop() directly, and move printing "Personalities" to md_seq_start(), "unsed devices" to md_seq_stop(): 1) md_seq_start print Personalities, and then set pos to first mddev; 2) md_seq_show show mddev; 3) md_seq_next update pos to next mddev; 4) loop 2-3 until the last mddev; 5) md_seq_stop print unsed devices; Signed-off-by: Yu Kuai <yukuai3@huawei.com> Signed-off-by: Song Liu <song@kernel.org> Link: https://lore.kernel.org/r/20230927061241.1552837-3-yukuai1@huaweicloud.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.
