Junxiao Bi f632881de1 aio: make kiocb->private NUll in init_sync_kiocb() ... commit 2dfd06036b upstream. Ocfs2 uses kiocb.*private as a flag of unsigned long size. In commit a11f7e6 ocfs2: serialize unaligned aio, the unaligned io flag is involved in it to serialize the unaligned aio. As *private is not initialized in init_sync_kiocb() of do_sync_write(), this unaligned io flag may be unexpectly set in an aligned dio. And this will cause OCFS2_I(inode)->ip_unaligned_aio decreased to -1 in ocfs2_dio_end_io(), thus the following unaligned dio will hang forever at ocfs2_aiodio_wait() in ocfs2_file_aio_write().
