+See upstream backported commit:

+ commit c4716bb296504cbc64aeefb370df44e821214c44

+
+ file: Rename fcheck lookup_fd_rcu
+
+ [ Upstream commit 460b4f812a9d473d4b39d87d37844f9fc30a9eb3 ]
+
+ Also remove the confusing comment about checking if a fd exists. I
+ could not find one instance in the entire kernel that still matches
+ the description or the reason for the name fcheck.
+
+ The need for better names became apparent in the last round of
+ discussion of this set of changes[1].
