Yes - it is set to yes in the smb.conf for both the global section and
the per share section

I also see that POSIX extensions in:
1) the server returns posix negotiation context in the SMB3.1.1
negotiate protocol response
2) the server returns the level 100 (FILE_POSIX_INFO) query info responses

But the (current Samba) server fails the level 100 (level 0x64 in hex)
FS_POSIX_INFO with "STATUS_INVALID_ERROR_CLASS"
which causes all xfstests to break since they can't verify the mount
(e.g. with "stat -f").
Nothing related to this on the client has changed, and ksmbd has
always supported this so works fine there.
