* sched/headers: Move cputime functionality from <linux/sched.h> and ↵Ingo Molnar2017-03-035-214/+214
| | | | | | | | | | | | | | | | | | | <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>.

| | | | | | | | | | | | | | 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.

* sched/headers: Move 'init_task' and 'init_thread_union' from <linux/sched.h> ↵Ingo Molnar2017-03-032-3/+6
| | | | | | | | | | | | | | | | 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.

* mm/headers, sched/headers: Move task related MM types from <linux/mm_types.> ↵Ingo Molnar2017-03-032-49/+55
| | | | | | | | | | | | | | | | | | | 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>.

| | | | | | | | | | | | | | | | | | | | | | <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.

* sched/headers: Move task_struct::signal and task_struct::sighand types and ↵Ingo Molnar2017-03-0312-501/+520
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | accessors into <linux/sched/signal.h> task_struct::signal and task_struct::sighand are pointers, which would normally make it straightforward to not define those types in sched.h. That is not so, because the types are accompanied by a myriad of APIs (macros and inline functions) that dereference them. Split the types and the APIs out of sched.h and move them into a new header, <linux/sched/signal.h>. With this change sched.h does not know about 'struct signal' and 'struct sighand' anymore, trying to put accessors into sched.h as a test fails the following way: ./include/linux/sched.h: In function ‘test_signal_types’: ./include/linux/sched.h:2461:18: error: dereferencing pointer to incomplete type ‘struct signal_struct’ ^ This reduces the size and complexity of sched.h significantly. Update all headers and .c code that relied on getting the signal handling functionality from <linux/sched.h> to include <linux/sched/signal.h>. The list of affected files in the preparatory patch was partly generated by grepping for the APIs, and partly by doing coverage build testing, both all[yes|mod|def|no]config builds on 64-bit and 32-bit x86, and an array of cross-architecture builds. Nevertheless some (trivial) build breakage is still expected related to rare Kconfig combinations and in-flight patches to various kernel code, but most of it should be handled by this patch.

* sched/headers: Prepare to remove spurious <linux/sched.h> inclusion dependenciesIngo Molnar2017-03-024-0/+4
| | | | | | | | | | | | | | | | | | | 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.
