We don't actually need the full rculist.h header in sched.h anymore, we will be able to include the smaller rcupdate.h header instead. But first update code that relied on the implicit header inclusion. Acked-by:

sched/headers: Prepare to move 'init_task' and 'init_thread_union' from <linux/sched.h> to <linux/sched/task.h> Update all usage sites first. Acked-by:

Update code that relied on sched.h including various MM types for them. This will allow us to remove the <linux/mm_types.h> include from <linux/sched.h>. Acked-by:

We are going to separate all the MM types that are embedded directly in 'struct task_struct' into the new <linux/mm_types_task.h> header. Create a new <linux/mm_types_task.h> that only contains some includes from mm_types.h itself. This should be trivially correct and easy to bisect to. (This patch does not materially move the types yet.) Acked-by:

Instead of including the full <linux/signal.h>, we are going to include the types-only <linux/signal_types.h> header in <linux/sched.h>, to further decouple the scheduler header from the signal headers. This means that various files which relied on the full <linux/signal.h> need to be updated to gain an explicit dependency on it. Update the code that relies on sched.h's inclusion of the <linux/signal.h> header. Acked-by:

Add #include <linux/cred.h> dependencies to all .c files rely on sched.h doing that for them. Note that even if the count where we need to add extra headers seems high, it's still a net win, because <linux/sched.h> is included in over 2,200 files ... Acked-by:

sched/headers: Prepare header dependency changes, move the <asm/paravirt.h> include to kernel/sched/sched.h Recent header reorganizations unearthed this hidden dependency: kernel/sched/core.c:199:25: error: 'paravirt_steal_rq_enabled' undeclared (first use in this function) kernel/sched/core.c:200:11: error: implicit declaration of function 'paravirt_steal_clock' [-Werror=implicit-function-declaration] So move the asm/paravirt.h include from kernel/sched/cpuclock.c to kernel/sched/sched.h. ( NOTE: We do this change before doing the changes that introduce the build failure, so the series remains fully bisectable. ) Reported-by:kbuild test robot <fengguang.wu@intel.com> Acked-by:

<linux/kasan.h> is a low level header that is included early in affected kernel headers. But it includes <linux/sched.h> which complicates the cleanup of sched.h dependencies. But kasan.h has almost no need for sched.h: its only use of scheduler functionality is in two inline functions which are not used very frequently - so uninline kasan_enable_current() and kasan_disable_current(). Also add a <linux/sched.h> dependency to a .c file that depended on kasan.h including it. This paves the way to remove the <linux/sched.h> include from kasan.h. Acked-by:

mm/vmacache, sched/headers: Introduce 'struct vmacache' and move it from <linux/sched.h> to <linux/mm_types> The <linux/sched.h> header includes various vmacache related defines, which are arguably misplaced. Move them to mm_types.h and minimize the sched.h impact by putting all task vmacache state into a new 'struct vmacache' structure. No change in functionality. Acked-by:
