[ Upstream commit a53936361330e4c55c0654605178281387d9c761 ] Commit3c6c2bebef("f2fs: avoid punch_hole overhead when releasing volatile data") introduced FI_FIRST_BLOCK_WRITTEN as below reason: This patch is to avoid some punch_hole overhead when releasing volatile data. If volatile data was not written yet, we just can make the first page as zero. After commit7bc155fec5("f2fs: kill volatile write support"), we won't support volatile write, but it missed to remove obsolete FI_FIRST_BLOCK_WRITTEN, delete it in this patch.

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.
