Ingo Molnar authored
sched/headers, mm: Move 'struct tlbflush_unmap_batch' from <linux/sched.h> to <linux/mm_types_task.h> Unclutter <linux/sched.h> some more. Also move the CONFIG_ARCH_WANT_BATCHED_UNMAP_TLB_FLUSH condition inside the structure body definition, to remove a pair of #ifdefs from sched.h. Acked-by:

trap_init() and cpu_init() belong into <linux/cpu.h>, sched_init*() into <linux/sched/init.h>. Acked-by:

Ingo Molnar authored
These two functions are task management related, not core scheduler APIs. Acked-by:
-
Ingo Molnar authored
This is a task-stack related API, not core scheduler functionality. Acked-by:

sched/headers, vfs/execve: Move the do_execve*() prototypes from <linux/sched.h> to <linux/binfmts.h> These are not scheduler related. Acked-by:
-
Ingo Molnar authored
sched/headers: Move sched_info_on() and force_schedstat_enabled() from <linux/sched.h> to <linux/sched/stat.h> These APIs are not core scheduler but scheduler statistics related. Acked-by:
-
Ingo Molnar authored
sched/headers: Move cputime functionality from <linux/sched.h> and <linux/cputime.h> into <linux/sched/cputime.h> Move cputime related functionality out of <linux/sched.h>, as most code that includes <linux/sched.h> does not use that functionality. Move data types that are not included in task_struct directly to the signal definitions, into <linux/sched/signal.h>. Also merge the (small) existing <linux/cputime.h> header into <linux/sched/cputime.h>. Acked-by:

Ingo Molnar authored
The task_lock()/task_unlock() APIs are not realated to core scheduling, they are task lifetime APIs, i.e. they belong into <linux/sched/task.h>. Move them. Acked-by:
-
Ingo Molnar authored
sched/headers: Move 'init_task' and 'init_thread_union' from <linux/sched.h> to <linux/sched/task.h> 'init_task' is really not part of core scheduler APIs but part of the fork() interface between the scheduler and process management. So move the declarations. Acked-by:

Ingo Molnar authored
Use the freshly introduced, reduced size <linux/mm_types_task.h> header instead. Acked-by:

Ingo Molnar authored
mm/headers, sched/headers: Move task related MM types from <linux/mm_types.> to <linux/mm_types_task.h> Separate all the MM types that are embedded directly in 'struct task_struct' into the <linux/mm_types_task.h> header. The goal is to include this header in <linux/sched.h>, not the full <linux/mm_types.h> header, to reduce the size, complexity and coupling of <linux/sched.h>. (This patch does not change <linux/sched.h> yet.) Acked-by:
-
Ingo Molnar authored
Separate out just the pure data types - sched.h will be able to use this reduced size header. Acked-by:
-
Ingo Molnar authored
Also remove the duplicate declaration from <linux/init_task.h>. ( That declaration was originally duplicated for dependency hell reasons, but there's no problem including the much smaller <linux/sched/autogroup.h> header now, to pick up the right prototype. ) Acked-by:
-
Ingo Molnar authored
Split out the task->stack related functionality, which is not really part of the core scheduler APIs. Only keep task_thread_info() because it's used by sched.h. Update the code that uses those facilities. Acked-by:
-
Ingo Molnar authored
These defines are not really part of the scheduler's driver API, but are related to the preempt count - so move them to <linux/preempt.h>. Acked-by:
-
Ingo Molnar authored
Most of the structure predeclarations were at the head of sched.h, but not all of them - there were a number of lines spread around sched.h, in random places. Move them to the head, and also sort them alphabetically. Remove unused entries. Acked-by:
-
Ingo Molnar authored
Move rcu_copy_process() into kernel/fork.c, which is the only user of this inline function. This simplifies <linux/sched/task.h> to the level that <linux/sched.h> does not have to be included in it anymore - which change is done in a subsequent patch. Acked-by:
-
Ingo Molnar authored
There's a fair amount of task lifetime management (a.k.a fork()/exit()) related APIs in <linux/sched.h>, but only a small fraction of the users of the generic sched.h header make use of them. Move these functions to the <linux/sched/task.h> header. Acked-by:
-
Ingo Molnar authored
Split the CPU hotplug scheduler APIs out of the common header. Acked-by:

Ingo Molnar authored
sched/headers: Move <asm/current.h> include from the middle of <linux/sched.h> to the header portion Linux-0.01 already defined 'current' in the middle of sched.h, so this is an ancient historical precedent - but still in a modern kernel it looks a bit weird that we have: #include <asm/current.h> in the middle of the header. Move it further up. If this was done for some obscure dependency reasons then we'll trigger and document it. Acked-by:

sched/headers, time/timekeeping: Move the xtime_update() prototype from <linux/sched.h> to <linux/time.h> This was in <linux/sched.h> only for hysterical raisins. Acked-by:
-
Ingo Molnar authored
Collect the various scheduler and task state debugging APIs scattered around <linux/sched.h> into the new <linux/sched/debug.h> header. In particular the show_regs() and show_stack() prototype affects many files, update them. Acked-by:
-
Ingo Molnar authored
There's a number of NOHZ/dyntics related functionality in <linux/sched.h>, but only a handful of timer files are making use of them. Move them into their own header. This better documents these APIs and unclutters <linux/sched.h>. Acked-by:
-
Ingo Molnar authored
There are a number of task statistics related variables and methods exported via sched.h - collect them into <linux/sched/stat.h> and include it from their usage sites. Acked-by:
-
Ingo Molnar authored
In preparation to remove the <linux/gfp.h> include from <linux/sched.h>. Acked-by:

sched/headers: Move signal wakeup & sigpending methods from <linux/sched.h> into <linux/sched/signal.h> This reduces the size of <linux/sched.h>. Acked-by:
-
Ingo Molnar authored
The CONFIG_TASK_XACCT=y accounting inline functions are only used by fs/read_write.c, so move them into their separate header. Acked-by:

Remove the following header inclusions from <linux/sched.h>: #include <asm/param.h> #include <linux/threads.h> #include <linux/kernel.h> #include <linux/types.h> #include <linux/timex.h> #include <linux/jiffies.h> #include <linux/rbtree.h> #include <linux/thread_info.h> #include <linux/cpumask.h> #include <linux/errno.h> #include <linux/nodemask.h> #include <linux/preempt.h> #include <asm/page.h> #include <linux/smp.h> #include <linux/compiler.h> #include <linux/completion.h> #include <linux/percpu.h> #include <linux/topology.h> #include <linux/rcupdate.h> #include <linux/time.h> #include <linux/timer.h> #include <linux/llist.h> #include <linux/uidgid.h> #include <asm/processor.h> because they are either not required, or are already included naturally as part of the remaining headers.

Only a small fraction of sched.h users actually utilizes these defines, and they are not scheduler functionality in any case, so move them into their separate header. (Also make <linux/sched/jobctl.h> a self-contained header.) Acked-by:
-
Ingo Molnar authored
sched/headers: Move the NUMA balancing interfaces from <linux/sched.h> to <linux/sched/numa_balancing.h> Split out the interface between the scheduler and the MM which deals with page fault driven NUMA balancing, into the new <linux/sched/numa_balancing.h> header. Acked-by:
-
Ingo Molnar authored
The in_vfork() function deals with task->mm, so it better belongs into <linux/sched/mm.h>. Acked-by:

Neither the mmap_layout nor the mm_update_next_owner() methods need to be in <linux/sched.h> - move them to the more appropriate <linux/sched/mm.h> header. Acked-by:
-
Ingo Molnar authored
No need to have this in the generic <linux/sched.h> header. Acked-by:
-
Ingo Molnar authored
sched/headers: Move 'struct pacct_struct' and 'struct cpu_itimer' form <linux/sched.h> to <linux/sched/signal.h> These structures are actually part of 'struct signal', so move them to <linux/sched/signal.h> where they belong. This further decreases the size and complexity of <linux/sched.h>. Acked-by:
-
Ingo Molnar authored
These methods don't belong into <linux/sched.h>, they are neither directly related to task_struct or are scheduler functionality. Put them next to the other watchdog methods in <linux/nmi.h>. ( Arguably that header's name is a misnomer, and this patch makes it more so - but it should be renamed in another patch. ) Acked-by:
-
Ingo Molnar authored
'struct user_struct' was added to sched.h historically, but it's actually entirely independent of task_struct and of scheduler details, so move it to its own header. Fix up .c files using those facilities. Acked-by:
