f2fs: use extent cache to optimize f2fs_reserve_block In some cases, we only need the block address when we call f2fs_reserve_block, other fields of struct dnode_of_data aren't necessary. We can try extent cache first for such cases in order to speed up the process. Signed-off-by: Fan li <fanofcode.li@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
