From: Bean Huo <beanhuo@xxxxxxxxxx>
Originally inode is used to get blksize, after commit 45bce8f3e343
("fs/buffer.c: make block-size be per-page and protected by the page lock"),
__block_commit_write no longer uses this parameter inode, this patch is to
remove inode and clean up block_commit_write.
