Make the FreeBSD and Linux compat code convert the parameters to their
native representation and call the native routines.
Remove KAUTH_PROCESS_SCHEDULER_GET/SET.
Update documentation and examples.
XXX: For now, only the Linux compat code does the priority conversion
XXX: right.
Linux priority conversion code from yamt@, thanks!
Okay yamt@.
words, don't pass an action and a request, and just use a single action to
indicate what is the operation in question.
This is the first step in fixing PR/37986, which calls for policy/priority
checking in the secmodel code. Right now we're lacking room for another
parameter required to make a decision, and this change makes room for such.
- revert struct sched_param changes to restore ABI.
- instead, add 'policy' arguments to _sched_{get,set}param syscalls.
(this is an API/ABI change.)
- correct kauth_authorize_process arguments.
while i'm here,
- don't bother to kmem_alloc for 4-byte structure.
in-kernel priority is used. Reported by <drochner>.
Minor fixes for scheduling calls to conform the POSIX:
- If pid is equal to zero, use the calling process;
- In case of permission problem, return EPERM instead of EACESS;
- sched_setscheduler() should return previously used policy;
- pthread_* calls should return the error code or zero;
Should fix the namespace problems (and builds of some packages):
- Move cpuset_t defintion from pset.h to sched.h;
- Remove the #include of pset.h in pthread.h;
Add schedctl(8) - a program to control scheduling of processes and threads.
Notes:
- This is supported only by SCHED_M2;
- Migration of LWP mechanism will be revisited;

int foo(struct lwp *l, void *v, register_t *retval)
to:
int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.
