Move scheduler ABI types (struct sched_attr, struct sched_param, etc.) into the new UAPI header. This further reduces the size and complexity of <linux/sched.h>. Acked-by:

sched/headers, delayacct: Move the 'struct task_delay_info' definition from <linux/sched.h> to <linux/delayacct.h> The 'struct task_delay_info' definition does not have to be in sched.h, because task_struct only has a pointer to it. So move it to <linux/delayacct.h> to reduce the size of <linux/sched.h>. Acked-by:

Move the sched_clock interfaces into a separate header file, to reduce the size of sched.h. Include <linux/sched/clock.h> in all files that made use of one of the Acked-by:

Further reduce the size of <linux/sched.h> by moving these APIs: tsk_is_polling() __current_set_polling() current_set_polling_and_test() __current_clr_polling() current_clr_polling_and_test() current_clr_polling() Acked-by:

The vast majority of sched.h users does not require the topology types and interfaces, so split them out into <linux/sched/topology.h>. This reduces the size of linux/sched.h by ~6%. Acked-by:

In the following patches we are going to remove various headers from sched.h and other headers that sched.h includes. To make those patches build cleanly prepare the scene by adding dependencies to various files that learned to rely on those to-be-removed dependencies. These changes all make sense standalone: they add a header for a data type that a particular .c or .h file is using. Acked-by:

sched/headers: Prepare to move cputime functionality from <linux/sched.h> into <linux/sched/cputime.h> Introduce a trivial, mostly empty <linux/sched/cputime.h> header to prepare for the moving of cputime functionality out of sched.h. Update all code that relies on these facilities. Acked-by:

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:

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:
-
Ingo Molnar authored
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:

Ingo Molnar authored
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:

We are going to split <linux/sched/task_stack.h> out of <linux/sched.h>, which will have to be picked up from other headers and a couple of .c files. Create a trivial placeholder <linux/sched/task_stack.h> file that just maps to <linux/sched.h> to make this patch obviously correct and bisectable.

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:
