From adbccddb4a16b1dbf047d330ae1e78fd1ec80352 Mon Sep 17 00:00:00 2001 From: "Joel Fernandes (Google)" Date: Sat, 22 Sep 2018 19:41:26 -0400 Subject: rcu: Fix rcu_{node,data} comments about gp_seq_needed Recent changes have removed the old ->gp_seq_needed field from the rcu_state structure, which in turn obsoleted a couple of comments in the rcu_node and rcu_data structures. This commit therefore updates these comments accordingly. Signed-off-by: Joel Fernandes (Google) Cc: Signed-off-by: Paul E.
