SMB3: Honor 'posix' flag for multiuser mounts (5391b8e1) · Commits · 戴 / test

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.
