I find out other problem. After applying that patch, in part of the
beginning of overlayfs_clonepath function, new->dest variable is,
for example:
  "overlayfs:/home/karma/.local/share/lxc/ct01/rootfs:/home/karma/.local/share/lxc/ct02/delta0"

So, as the result, run "mkdir_p(new->dest, 0755)", and create dir in
current dir.

$ lxc-clone -o ct02 -n test -s -B overlayfs
lxc_container: conf.c: chown_mapped_root: 3649 Error stat /home/karma/.local/share/lxc/test/delta0
Created container test as snapshot of ct02
lxc_container: lxccontainer.c: copy_file: 2303 copy destination /home/karma/.local/share/lxc/test/lxc_rdepends exists
Created container test as snapshot of ct02
