ext4: make ext4_init_dot_dotdot for inline dir usage
Currently, the initialization of dot and dotdot are encapsulated in ext4_mkdir and also bond with dir_block. So create a new function named ext4_init_new_dir and the initialization is moved to ext4_init_dot_dotdot. Now it will called either in the normal non-inline case(rec_len of ".." will cover the whole block) or when we converting an inline dir to a block(rec len of ".." will be the real length). The start of the next entry is also returned for inline dir usage. Signed-off-by: Tao Ma <boyu.mt@taobao.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
