Hi, I was going through lov_pack.c and in the function lov_unpackmd before checking for lmm we are using the lmm_pattern value and doing allocation. In case lmm is null use of pattern = le32_to_cpu(lmm->lmm_pattern); will throw a null pointer exception. I was thinking of moving the null check above but i that case what will be the allocation pattern?
