Jinsu Lee reported a performance regression issue, after commit5c8764f867("f2fs: fix to force buffered IO on inline_data inode"), we forced direct write to use buffered IO on inline_data inode, it will cause performace regression due to memory copy and data flush. It's fine to not force direct write to use buffered IO, as it can convert inline inode before committing direct write IO. Fixes:5c8764f867("f2fs: fix to force buffered IO on inline_data inode") Reported-by: Jinsu Lee <jinsu1.lee@samsung.com> Closes: https://lore.kernel.org/linux-f2fs-devel/af03dd2c-e361-4f80-b2fd-39440766cf6e@kernel.org Signed-off-by: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
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 reStructuredText 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.
