>Subject: [PATCH] s3:smbclient: Allow last dos attribute to be cleared
>
>With the upgrade to SMB3.1.1 from cifs for smbclient,
>setmode no longer works when removing attributes,
>if the resultant attribute is 0 it is skipped
>(unlike for the old cifs setpathinfo).
>
>When clearing the final attribute, pass in ATTRIBUTE_NORMAL
>instead of zero.
>
>This also removes a redundant cli_setatr call
>when clearing attributes (cli_setatr was being called
>twice).
