SMB3: Honor 'posix' flag for multiuser mounts
commit 5391b8e1b7b7e5cfa2dd4ffdc4b8c6b64dfd1866 upstream. The flag from the primary tcon needs to be copied into the volume info so that cifs_get_tcon will try to enable extensions on the per-user tcon. At that point, since posix extensions must have already been enabled on the superblock, don't try to needlessly adjust the mount flags. Fixes: ce558b0e17f8 ("smb3: Add posix create context for smb3.11 posix mounts") Fixes: b326614ea215 ("smb3: allow "posix" mount option to enable new SMB311 protocol extensions") Signed-off-by: Paul Aurich <paul@darkrain42.org> Signed-off-by: Steve French <stfrench@microsoft.com> Reviewed-by: Aurelien Aptel <aaptel@suse.com> Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
