  To: Andrew Morton; +Cc: linux-fsdevel, autofs mailing list

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.
