Subject: [question] should 363b02dab09b3 be backported to stable 4.1+?

Hello David, Eric,

please help me out.

I'm looking at 363b02dab09b ("KEYS: Fix race between updating and finding
a negative key") right now. So, I see that it has been backported to stable
4.4+. My question is -- do we have those test_bit(KEY_FLAG_INSTANTIATED)
and test_bit(KEY_FLAG_NEGATIVE) races in stable 4.1?
