Dmitry Monakhov 4319fd0000 ext4: race-condition protection for ext4_convert_unwritten_extents_endio ... commit dee1f973ca upstream. We assumed that at the time we call ext4_convert_unwritten_extents_endio() extent in question is fully inside [map.m_lblk, map->m_len] because it was already split during submission. But this may not be true due to a race between writeback vs fallocate. If extent in question is larger than requested we will split it again. Special precautions should being done if zeroout required because [map.m_lblk, map->m_len] already contains valid data.
