[ Upstream commit 66110abc4c931f879d70e83e1281f891699364bf ] PG_checked flag will be set on data page during GC, later, we can recognize such page by the flag and migrate page to cold segment. But previously, we don't clear this flag when invalidating data page, after page redirtying, we will write it into wrong log. Let's clear PG_checked flag in set_page_dirty() to avoid this.

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.
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.
