Please try:
5ce5674187c3 ("xfs: convert delayed extents to unwritten when zeroing post eof blocks")
2e08371a83f1 ("xfs: make xfs_bmapi_convert_delalloc() to allocate the target offset")
fc8d0ba0ff5f ("xfs: make the seq argument to xfs_bmapi_convert_delalloc() optional")
bb712842a85d ("xfs: match lock mode in xfs_buffered_write_iomap_begin()")
