vn_rlimit_fsize takes uio->uio_offset and uio->uio_resid into account when determining whether given write would exceed RLIMIT_FSIZE. When APPEND flag is specified, ZFS updates uio->uio_offset to point to the end of file. But this happens after a call to vn_rlimit_fsize, so vn_rlimit_fsize check can be rendered ineffective by thread that opens some file with O_APPEND and lseeks below RLIMIT_FSIZE before calling write.
