[Linux 4.4.x] CIFS_POSIX cannot be enabled after commit 60da90b224ba7

["zhangyi (F)" <yi.zhang@xxxxxxxxxx>]

Hi Sasha Levin,

I notice that 4.4.169 merged 60da90b224ba7 ("cifs: In Kconfig CONFIG_CIFS_POSIX
needs depends on legacy (insecure cifs)") add a Kconfig dependency CIFS_ALLOW_INSECURE_LEGACY,
which was not defined in 4.4 stable, so after this patch we are not able to enable
CIFS_POSIX anymore. Linux 4.4 stable didn't merge the legacy dialects codes, so do we really
need this patch for 4.4?

Thanks,
Yi.
