Chao Yu 98df108a9a f2fs: compress: fix to cover f2fs_disable_compressed_file() w/ i_sem 
[ Upstream commit 2f9420d3a9 ]

- f2fs_disable_compressed_file
  - check inode_has_data
					- f2fs_file_mmap
					- mkwrite
					 - f2fs_get_block_locked
					 : update metadata in compressed
					   inode's disk layout
  - fi->i_flags &= ~F2FS_COMPR_FL
  - clear_inode_flag(inode, FI_COMPRESSED_FILE);

we should use i_sem lock to prevent above race case.

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.

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.
