That's why it was highlighted in the changelog. Hopefully a
Thunderbolt developer can confirm if it is a non-issue.
Documentation/ABI/testing/sysfs-bus-thunderbolt does not seem to
answer this question about whether authorized_show and
authorized_store need to be symmetric.
Apparently, Bolt does read it [1] and cares about it [2].
Ah, thank you!
Yeah, looks like the conversion to bool was indeed too hopeful.
IIUC, the end result of value "2" in authorized sysfs is to just
"authorize" or "de-authorize". In that case, can the user space
driver adapt to this int->bool change? Just want to know the
possibility.
