I added some logging messages.

I got following logs on dmesg.

FS-Cache: Netfs 'smb2' unregistered from caching
====================================================
register_key_types returned -17 (EEXIST)
key "smb2" has already registered?
What should I do?

Thank you, Suresh and Steve.
Fscache was loaded, but smb2 module was not loaded successfully.
Nothing was displayed when I did
lsmod | grep smb2
From Dmesg, following messages were displayed.

Does this means FS-Cache on this kernel doesn't support smb2?
That is probably not the problem. Seems like init_smb2 is failing.
Perhaps a problem registering the required key types.
You could enable debug messages to see if additional info is logged
to dmesg
e.g.
stevef@stevef-laptop:~/smb2$ git diff -a
diff --git a/fs/smb2/smb2fs.c b/fs/smb2/smb2fs.c
index aa550a3..8cc1245 100644

Alternatively you could add some logging (e.g. printk statements)
to the error goto statements in this section of smb2fs.c (smb2_init)
rc = smb2_fscache_register();
if (rc)
goto out_clean_proc;
rc = smb2_init_inodecache();
if (rc)
goto out_unregister_fsc;
rc = smb2_init_mids();
if (rc)
goto out_destroy_inodecache;
rc = smb2_init_request_bufs();
if (rc)
goto out_destroy_mids;
rc = register_filesystem(&smb2_fs_type);
if (rc)
goto out_destroy_request_bufs;
rc = register_key_type(&smb2_spnego_key_type);
