I am trying to run lwext4_fs.run from world repo

it gives the following error on linux/x86_64
[init -> test-libc_vfs] calling open(file_name4, O_CREAT | O_WRONLY) file_name=test4.tst
[init -> test-libc_vfs] open(file_name4, O_CREAT | O_WRONLY) succeeded
[init -> test-libc_vfs] calling ftruncate(fd, 100)
[init -> test-libc_vfs] ftruncate(fd, 100) succeeded

[init -> test-libc_vfs] close(fd) succeeded
[init -> test-libc_vfs] calling stat(file_name4, &stat_buf) file_name=test4.tst
[init -> test-libc_vfs] stat(file_name4, &stat_buf) failed, ret=0, errno=2
[init -> test-libc_vfs] Error: Uncaught exception of type 'Test_failed'
[init -> test-libc_vfs] Warning: abort called - thread: ep
^Cmake: *** [Makefile:396: run/lwext4_fs] Error 130

can this error could be ignored?
is lwext4 port somhow usable in general on 21.11? 

can I utilise it as a main fs inside genode to store compilation results in rw mode?
