Such behaviour would require the inode to be removed from the radix tree, freed and then reallocated and reinitialised to a different identity within a single RCU grace period. That is impossible because the object we found during the lookup won't get freed until the RCU grace period ends sometime after we drop the rcu_read_lock().... Hence the right thing to do here is to remove this check completely and leave the rest of the code alone.... -Dave. -- Dave Chinner david@xxxxxxxxxxxxx
