Currently f2fs stats are only available from /d/f2fs/status. This patch adds some of the f2fs stats to sysfs so that they are accessible even when debugfs is not mounted. The following sysfs nodes are added: -/sys/fs/f2fs/<disk>/free_segments -/sys/fs/f2fs/<disk>/cp_foreground_calls -/sys/fs/f2fs/<disk>/cp_background_calls -/sys/fs/f2fs/<disk>/gc_foreground_calls -/sys/fs/f2fs/<disk>/gc_background_calls -/sys/fs/f2fs/<disk>/moved_blocks_foreground -/sys/fs/f2fs/<disk>/moved_blocks_background -/sys/fs/f2fs/<disk>/avg_vblocks Signed-off-by: Hridya Valsaraju <hridya@google.com> [Jaegeuk Kim: allow STAT_FS without DEBUG_FS] 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 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.
