zhengliang 196ba8a8ab f2fs: fix to data block override node segment by mistake 
The following race could lead to data block override node segment by mistake.

Task A            |    Task B         |  Task C            |    Task D
=======           |   ========        |==========          |  =========
open file         |                   |                    |
white file        |                   |                    |
submit bio        |                   |                    |
wait io complete  |                   |                    |
		  |   remove file     |                    |
........          |   iput_final      |                    |
		  |                   |   sync             |
		  |                   |  do checkpoint     |
		  |		      |  data segment free |
		  |                   |                    | create file1
		  |		      |		           | allocate node segment（if it is the same segment freed by Task C）
f2fs_write_end_io |		      |                    |

So we need to guarantee io complete before truncate inode
in f2fs_drop_inode.

README 

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.
