The following commit has been merged into the core/rcu branch of tip: Commit-ID: a2dae43088d51c4869e7fa91ca09bcc890e277fc Gitweb: https://git.kernel.org/tip/a2dae43088d51c4869e7fa91ca09bcc890e277fc Author: Wei Yang <richard.weiyang@xxxxxxxxxxxxxxxxx> AuthorDate: Fri, 12 Jun 2020 10:07:53 +08:00 Committer: Paul E. McKenney <paulmck@xxxxxxxxxx> CommitterDate: Mon, 29 Jun 2020 11:58:51 -07:00 rcu: grplo/grphi just records CPU number The ->grplo and ->grphi fields store the lowest and highest CPU number covered by to a rcu_node structure, which is not the group number. This commit therefore adjusts these fields' comments to match reality. Signed-off-by: Wei Yang <richard.weiyang@xxxxxxxxxxxxxxxxx> Signed-off-by: Paul E.
