Hello, I believe the pre-flip memory barrier is not required. The only reason I can say to remove it, other than the possibility that it is unnecessary, is to not have extra code that does not help. However, since we are issuing a fully memory-barrier after the flip, I cannot say that it hurts to do it anyway. For this reason, please consider these patches as "informational", than a "please merge". :-) Though, feel free to consider merging if you agree! All SRCU scenarios pass with these, with 6 hours of testing. thanks, - Joel Joel Fernandes (Google) (2): srcu: Remove comment about prior read lock counts srcu: Remove memory barrier "E" as it is not required kernel/rcu/srcutree.c | 10 ---------- 1 file changed, 10 deletions(-) -- 2.39.0.314.g84b9a713c41-goog
