| * Kill sched.h dependency on rcupdate.hKent Overstreet2023-12-2714-10/+28
| | | | | | | | | | | | | | by moving cond_resched_rcu() to rcupdate_wait.h, we can kill another big sched.h dependency. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

| * preempt.h: Kill dependency on list.hKent Overstreet2023-12-271-2/+4
| | | | | | | | | | | | We really only need types.h, list.h is big. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
| * rseq: Split out rseq.h from sched.hKent Overstreet2023-12-2710-124/+140
| | | | | | | | | | | | | | | | | | We're trying to get sched.h down to more or less just types only, not code - rseq can live in its own header. This helps us kill the dependency on preempt.h in sched.h. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
| * LoongArch: signal.c: add header file to fix build errorRandy Dunlap2023-12-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | loongarch's signal.c uses rseq_signal_deliver() so it should pull in the appropriate header to prevent a build error: ../arch/loongarch/kernel/signal.c: In function 'handle_signal': ../arch/loongarch/kernel/signal.c:1034:9: error: implicit declaration of function 'rseq_signal_deliver' [-Werror=implicit-function-declaration] 1034 | rseq_signal_deliver(ksig, regs); | ^~~~~~~~~~~~~~~~~~~ Fixes: b74baf4ad05b ("LoongArch: Add signal handling support") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Cc: Huacai Chen <chenhuacai@kernel.org> Cc: WANG Xuerui <kernel@xen0n.name> Cc: loongarch@lists.linux.dev Cc: Kent Overstreet <kent.overstreet@linux.dev> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
| * restart_block: Trim includesKent Overstreet2023-12-212-1/+2
| | | | | | | | | | | | | | | | | | We don't actually use any timekeeping types, no need to pull in time64.h. Also, sched.h uses restart_block; add it as a direct dependency. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
| * lockdep: move held_lock to lockdep_types.hKent Overstreet2023-12-212-57/+57
| | | | | | | | | | | | | | | | held_lock is embedded in task_struct, and we don't want sched.h pulling in all of lockdep.h Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev> Acked-by: Waiman Long <longman@redhat.com>

| * uapi/linux/resource.h: fix includeKent Overstreet2023-12-211-1/+1
| | | | | | | | | | | | | | We should't be depending on time.h; we should only be pulling in other uapi headers. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
| * x86/signal: kill dependency on time.hKent Overstreet2023-12-211-1/+0
| | | | | | | | | | | | this is unecessary, and was pulling in printk.h from uapi headers Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
| * syscall_user_dispatch.h: split out *_types.hKent Overstreet2023-12-213-9/+24
| | | | | | | | | | | | | | thread_info.h pulls in a lot of junk that sched.h that we don't need; in particular, this helps to kill the printk.h dependency. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

| * ipc: Kill bogus dependency on spinlock.hKent Overstreet2023-12-212-1/+3
| | | | | | | | | | | | | | pruning sched.h dependencies, headers shouldn't pull in more than they need. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
| * shm: Slim down dependenciesKent Overstreet2023-12-215-2/+6
| | | | | | | | | | | | list_head is in types.h, not list.h., and the uapi header wasn't needed. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

| * timers: Split out timer_types.hKent Overstreet2023-12-212-15/+24
| | | | | | | | | | | | | | | | Cutting down on sched.h dependencies: this is going to be used in workqueue_types.h in the next patch, so we can kill the sched.h dependency on workqueue.h. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

| | | | | | | | | | | | | | | | Trimming down sched.h dependencies: timerqueue_types can include just rbtree_types.h instead of pulling in rbtree.h. Cc: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>
| * rslib: kill bogus dependency on list.hKent Overstreet2023-12-211-1/+0

| * wait: Remove uapi header file from main header fileMatthew Wilcox (Oracle)2023-12-213-2/+4
| | | | | | | | | | | | | | | | | | | | There's really no overlap between uapi/linux/wait.h and linux/wait.h. There are two files which rely on the uapi file being implcitly included, so explicitly include it there and remove it from the main header file.

| * hrtimers: Split out hrtimer_types.hKent Overstreet2023-12-213-43/+53
| | | | | | | | | | | | | | | | We need to reduce the scope of what's included in sched.h: task_struct includes a hrtimer, so split out the core types into their own header. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev> Cc: Thomas Gleixner <tglx@linutronix.de>
| * ktime.h: move ktime_t to types.hKent Overstreet2023-12-212-5/+6

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sched.h, which defines task_struct, needs nodemask_t - but sched.h is a frequently used header and ideally shouldn't be pulling in any more code that it needs to. This splits out nodemask_types.h which has the definition sched.h needs, which will avoid a circular header dependency in the alloc tagging patch series, and as a bonus should speed up kernel build times.
