Return SMB2_CREATE_FLAG_REPARSEPOINT in create response

[Carson Buttars]

Hello all,

I just completed the mountpoint detection patch I've been working on, 
and feedback on it would be great. Here is a link to it: 3141 
<https://gitlab.com/samba-team/samba/-/merge_requests/3141>.

In working on this, I also stumbled upon the 
SMB2_CREATE_FLAG_REPARSEPOINT (MS-SMB2 2.2.14 
<https://learn.microsoft.com/en-us/openspecs/windows_protocols/ms-smb2/d166aa9e-0b53-410e-b35e-3933d8131927>) 
field in the create request, and it seems to not be implemented in any 
way. There's not a lot of information on it, but as far as I understand, 
it should be returned if the requested file is opened without the 
FILE_OPEN_REPARSE_POINT create option and the file is a in fact a 
reparse point. Am I understanding that right? Is there a good reason to 
or to not implement it?

Thanks,

Carson Buttars
