Merge branch 'work.sys_wait' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs

2017-07-05T21:10:19+00:00

Pull wait syscall updates from Al Viro: "Consolidating sys_wait* and compat counterparts. Gets rid of set_fs()/double-copy mess, simplifies the whole thing (lifting the copyouts to the syscalls means less headache in the part that does actual work - fewer failure exits, to start with), gets rid of the overhead of field-by-field __put_user()" * 'work.sys_wait' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: osf_wait4: switch to kernel_wait4() waitid(): switch copyout of siginfo to unsafe_put_user() wait_task_zombie: consolidate info logics kill wait_noreap_copyout() lift getrusage() from wait_noreap_copyout() waitid(2): leave copyout of siginfo to syscall itself kernel_wait4()/kernel_waitid(): delay copying status to userland wait4(2)/waitid(2): separate copying rusage to userland move compat wait4 and waitid next to native variants

sched/core: Drop the unused try_get_task_struct() helper function

2017-06-20T10:48:37+00:00

This function was introduced by: 150593bf8693 ("sched/api: Introduce task_rcu_dereference() and try_get_task_struct()") ... to allow easier usage of task_rcu_dereference(), however no users were ever added. Drop the helper.

osf_wait4: switch to kernel_wait4()

sched/headers: Move the sched_exec() prototype to

2017-03-03T00:45:26+00:00

sched_exec() better fits into the task lifetime APIs than into the core scheduler APIs. This reduces the size of a bit. Acked-by: Linus Torvalds Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar

sched/headers: Move the get_task_struct()/put_task_struct() and related APIs from to

2017-03-03T00:45:26+00:00

These belong into the task lifetime API header. Acked-by: Linus Torvalds Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar

sched/headers: Move exit_files() and exit_itimers() from to

2017-03-03T00:45:24+00:00

These two functions are task management related, not core scheduler APIs. Acked-by: Linus Torvalds Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar

sched/headers: Move the task_lock()/unlock() APIs to

2017-03-03T00:45:22+00:00

The task_lock()/task_unlock() APIs are not realated to core scheduling, they are task lifetime APIs, i.e. they belong into . Move them. Acked-by: Linus Torvalds Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar

sched/headers: Move 'init_task' and 'init_thread_union' from to

2017-03-03T00:45:22+00:00

'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.

sched/headers, RCU: Move rcu_copy_process() from to kernel/fork.c

2017-03-03T00:43:46+00:00

Move rcu_copy_process() into kernel/fork.c, which is the only user of this inline function. This simplifies to the level that does not have to be included in it anymore - which change is done in a subsequent patch.

sched/headers: Move task lifetime APIs from to

2017-03-03T00:43:45+00:00

There's a fair amount of task lifetime management (a.k.a fork()/exit()) related APIs in , but only a small fraction of the users of the generic sched.h header make use of them. Move these functions to the header. Acked-by: Linus Torvalds Cc: Mike Galbraith Cc: Peter Zijlstra Cc: Thomas Gleixner Cc: linux-kernel@vger.kernel.org Signed-off-by: Ingo Molnar
