rcu: Fix rcu_{node,data} comments about gp_seq_needed (adbccddb) · Commits · 戴 / test

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:
