[PATCH] This patch fixes the warning generated due to use of symbolic

[Aviral Gupta <shiv14112001@gmail.com>]

It's better to use octal permissons instead of symbolic ones because  peoples are more
familiar with octal permissons.
WARNING: Symbolic permissions 'S_IRUGO | S_IWUSR' are not preferred. Consider using octal permissions '0644'.
+	md->force_ro.attr.mode = S_IRUGO | S_IWUSR;

WARNING: Symbolic permissions 'S_IRUGO' are not preferred. Consider using octal permissions '0444'.
+			mode = S_IRUGO;

WARNING: Symbolic permissions 'S_IRUGO | S_IWUSR' are not preferred. Consider using octal permissions '0644'.
+			mode = S_IRUGO | S_IWUSR;

WARNING: Symbolic permissions 'S_IRUSR' are not preferred. Consider using octal permissions '0400'.
