Joseph Qi 32e5a2a2be ocfs2: fix shift left overflow ... When using a large volume, for example 9T volume with 2T already used, frequent creation of small files with O_DIRECT when the IO is not cluster aligned may clear sectors in the wrong place. This will cause filesystem corruption. This is because p_cpos is a u32. When calculating the corresponding sector it should be converted to u64 first, otherwise it may overflow.
