If kernel ignores PT then value of PT isn't affect anything, so there is no need in keeping it same as XATTR value. I was affected by the issue because while XATTR value was correct it doesn't really works because I had EMUTRAMP disabled in kernel (so "E" flag which mean "enable EMUTRAMP" has no effect). -- WBR, Alex.
