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).
