Re: [Samba] 32 seconds vs 72 minutes -- expected performance difference?

I've enabled verbose/debug logging on the client side. Here are a few
operations from the log, and my observations on them:

1) Why is the log saying `SMB2` everywhere? Shouldn't it be saying `SMB3`?
2) Is this normal -- fs/cifs/smb2misc.c: Calculated size 157 length 156
mismatch mid 11907
3) Is this normal -- fs/cifs/misc.c: Null buffer passed to
cifs_small_buf_release
4) Is this normal --
          fs/cifs/readdir.c: index not in buffer - could not findnext into
it
          fs/cifs/readdir.c: could not find entry
5) This definitely seems like some error, right? -- fs/cifs/smb2maperror.c:
Mapping SMB2 status code 0x80000006 to POSIX err -61

There is also another data point which _might_ be relevant. It _seems_ that
"systemd-resolved" is randomly crashing on the server , possibly because of
the mounted samba share. Caveat: I am not completely sure about the
correlation between samba mount and systemd-resolved crashes. Nevertheless,
I had already asked this question on StackExchange at
https://askubuntu.com/questions/1117842/systemd-resolved-crashing-with-failed-to-set-up-mount-namespacing-invalid-argu
if you feel that this might be relevant. Further, I can confirm that
systemd-resolved had NOT crashed when the following logs were obtained:

## OPERATION 1 -  `ls debug.log` -- simply listing a single file. Does
anything seem wrong with this?
