ocfs2: Write support for directories with inline data
Create all new directories with OCFS2_INLINE_DATA_FL and the inline data bytes formatted as an empty directory. Inode size field reflects the actual amount of inline data available, which makes searching for dirent space very similar to the regular directory search. Inline-data directories are automatically pushed out to extents on any insert request which is too large for the available space.
