Xiao Ni 9be148e408 async_xor: check src_offs is not NULL before updating it ... When PAGE_SIZE is greater than 4kB, multiple stripes may share the same page. Thus, src_offs is added to async_xor_offs() with array of offsets. However, async_xor() passes NULL src_offs to async_xor_offs(). In such case, src_offs should not be updated. Add a check before the update.
