Previously, we added a parameter @map.m_may_create to trigger OPU
allocation and call f2fs_balance_fs() correctly.
But in get_more_blocks(), @create has been overwritten by below code.
So the function f2fs_map_blocks() will not allocate new block address
but directly go out. Meanwile,there are several functions calling
f2fs_map_blocks() directly and @map.m_may_create not initialized.
CODE:
create = dio->op == REQ_OP_WRITE;
if (dio->flags & DIO_SKIP_HOLES) {
if (fs_startblk <= ((i_size_read(dio->inode) - 1) >>
i_blkbits))
create = 0;
}
This patch fixes it.

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.
