Previously, during foreground GC, if victims contain data of pinned file, it will fail migration of the data, and meanwhile i_gc_failures of that pinned file may increase, and when it exceeds threshold, GC will unpin the file, result in breaking pinfile's semantics. In order to mitigate such condition, let's record and skip section which has pinned file's data and give priority to select unpinned one.

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.
