mainlining shenanigans

When viewing the page owner information, we expect that the information can be sorted by PID, so that we can quickly combine PID with the program to check the information together. We also expect that the information can be sorted by time. Time sorting helps to view the running status of the program according to the time interval when the program hangs up. Finally, we hope to pass the page_ owner_ Sort. C can reduce part of the output and only output the plate information whose memory has not been released, which can make us locate the problem of the program faster. Therefore, the following adjustments have been made: 1. Add the static functions search_pattern and check_regcomp to improve the cleanliness. 2. Add member attributes and their corresponding sorting methods. In terms of comparison time, int will overflow because the data of ull is too large, so the ternary operator is used 3. Add the -f parameter to filter out the information of blocks whose memory has not been released Link: https://lkml.kernel.org/r/20211206165653.5093-1-zhaochongxi2019@email.szu.edu.cn Signed-off-by: Chongxi Zhao <zhaochongxi2019@email.szu.edu.cn> Reviewed-by: Sean Anderson <seanga2@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

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.
