On most kernels `nr_inodes=1` works fine. However, Ubuntu 20.04 (Focal) with the official 5.4 kernel carries a private patch in mm/shmem.c that rejects "nr_inodes<2", so let's keep `nr_inodes=2` here!

We don't know whether some kernels will fail with "nr_blocks=1,nr_inodes=2", so let's fall back to the old runc behavior of mounting a tmpfs without these options. Signed-off-by: lifubang <lifubang@acmcoder.com> (cherry picked from commit 67e6a11) Signed-off-by: lifubang <lifubang@acmcoder.com>
