So rcupdate.h is a pretty complex header, in particular it includes <linux/completion.h> which includes <linux/wait.h> - creating a dependency that includes <linux/wait.h> in <linux/sched.h>, which prevents the isolation of <linux/sched.h> from the derived <linux/wait.h> header. Solve part of the problem by decoupling rcupdate.h from completions: this can be done by separating out the rcu_synchronize types and APIs, and updating their usage sites. Since this is a mostly RCU-internal types this will not just simplify <linux/sched.h>'s dependencies, but will make all the hundreds of .c files that include rcupdate.h but not completions or wait.h build faster. ( For rcutiny this means that two dependent APIs have to be uninlined, but that shouldn't be much of a problem as they are rare variants. ) Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul E.
