Hi Ted,
No we don't need the patch. The patch is wrong. We are actually taking

3033 */
3034 if (!(ac->ac_flags & EXT4_MB_DELALLOC_RESERVED))
3035 /* release all the reserved blocks if non delalloc */
3036 percpu_counter_sub(&sbi->s_dirtyblocks_counter, reserv_blks);
3037 else {
3038 percpu_counter_sub(&sbi->s_dirtyblocks_counter,
3039 ac->ac_b_ex.fe_len);
