McKenney <paulmck@xxxxxxxxxxxxxxxxxx> CommitDate: Thu, 8 Jun 2017 18:52:37 -0700 rcu: Refactor #includes from include/linux/rcupdate.h The list of #includes from include/linux/rcupdate.h has grown quite a bit, so it is time to trim it. This commit moves the #include of include/linux/ktime.h to include/linux/rcutiny.h, along with the Tiny-RCU-only function that was the only thing needing ktimem.h. It then reconstructs the files included into include/linux/ktime.h based on what is actually needed, with significant help from the 0day Test Robot. This single change reduces the .i file footprint from rcupdate.h from 9018 lines to 7101 lines. Reported-by: Ingo Molnar <mingo@xxxxxxxxxx> Signed-off-by: Paul E.
