4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Ian Kent <ra...@themaw.net> commit 1e6306652ba18723015d1b4967fe9de55f042499 upstream. The autofs file system mkdir inode operation blindly sets the created directory mode to S_IFDIR | 0555, ingoring the passed in mode, which can cause selinux dac_override denials. But the function also checks if the caller is the daemon (as no-one else should be able to do anything here) so there's no point in not honouring the passed in mode, allowing the daemon to set appropriate mode when required.
