Careful with this, you can't backport this to any kernels that don't have the sysfs ops locking changes or they will crash in sysfs code.
Oops, I was way too fast! Thanks Jason.
Hmm... hold on a second.
How would the crash realize? I mean this is at the point when user space should not be active.
Not strictly, AFAIK
Secondly, why the crash would not realize with TPM2? The only thing the fix is doing is to do the same thing with TPM1 essentially.
TPM2 doesn't use the unlocked sysfs path
