Chao Yu a2e2e76b23 f2fs: fix to drop all inmem pages correctly
In commit 57864ae5ce ("f2fs: limit # of inmemory pages"), we have
limited memory footprint of all inmem pages with 20% of total memory,
otherwise, if we exceed the threshold, we will try to drop all inmem
pages to avoid excessive memory pressure resulting in performance
regression.

But in some unrelated error paths, we will also drop all inmem pages,
which should be wrong, fix it in this patch.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
