Cover letter [PATCH 0/2] key payload access with just rcu_read_lock()

Hi David,

this is a follow-up for "suspicious RCU usage" warning described in these 2 linux-nfs threads:
http://marc.info/?t=147558830300003&r=1&w=2
http://marc.info/?t=148776770500001&r=1&w=2

Did you have something like in mind?

Thanks,
Jan
