    f2fs: Add f2fs stats to sysfs · fc7100ea
    Hridya Valsaraju authored
    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
