Merge branch 'rfs-lockless-annotate'
Eric Dumazet says:
====================
rfs: annotate lockless accesses
rfs runs without locks held, so we should annotate
read and writes to shared variables.
It should prevent compilers forcing writes
in the following situation:
if (var != val)
var = val;
A compiler could indeed simply avoid the conditional:
var = val;
This matters if var is shared between many cpus.
v2: aligns one closing bracket (Simon)
adds Fixes: tags (Jakub)
