Remove __need_schedparam and __cpu_set_t_defined.
bits/sched.h has logic to expose only an impl-namespace variant of struct sched_param (i.e. struct __sched_param), but nothing uses it, and the only header that includes bits/sched.h is sched.h. The __need_schedparam logic can therefore be removed. bits/sched.h also has a great deal of code relating to cpu_set_t objects that was *almost* the same between the two versions of bits/sched.h in the tree; a little spelunking indicated that this is because some bug fixes got applied to the Linux-specific bits/sched.h but not the generic one. Introduce a new header, bits/cpu-set.h, containing the version of that code with the bugfixes, have sched.h include it directly, and delete all of the code from both versions of bits/sched.h. Also remove the unnecessary name mangling in the definition of struct sched_param -- POSIX specifies a field 'sched_priority', so there is no reason to define it as '__sched_priority' and then paper over that with a macro. (Just in case someone was using the internal name, 'sched_priority' remains a macro defined to expand to itself, and '__sched_priority' now expands to 'sched_priority'.) Finally, as long as I'm touching these files anyway, merge new constants from linux/sched.h into the Linux bits/sched.h. * bits/sched.h: Remove __need_schedparam logic and replace with a normal multiple-include guard. Change field name in struct sched_param from __sched_priority to sched_priority. Delete everything under #ifndef __cpu_set_t_defined. * sysdeps/unix/sysv/linux/bits/sched.h: Likewise. Also sync with kernel sched.h, adding SCHED_ISO and SCHED_DEADLINE constants. * posix/sched.h: Include bits/cpu-set.h as well as bits/sched.h. For compatibility, #define sched_priority to itself, and #define __sched_priority as sched_priority. * posix/bits/cpu-set.h: New file containing, verbatim, the code that was under #ifndef __cpu_set_t_defined in sysdeps/unix/sysv/linux/bits/sched.h. * include/bits/cpu-set.h: New wrapper. * posix/Makefile: Install bits/cpu-set.h.

* bits/sched.h: Remove __need_schedparam logic and replace with a
|
||||||
|
normal multiple-include guard. Change field name in struct
|
||||||
|
sched_param from __sched_priority to sched_priority. Delete
|

everything under #ifndef __cpu_set_t_defined.
|

|
* sysdeps/unix/sysv/linux/bits/sched.h: Likewise. Also sync with

kernel sched.h, adding SCHED_ISO and SCHED_DEADLINE constants.
|
||||||
|
|
||||||
|
* posix/sched.h: Include bits/cpu-set.h as well as bits/sched.h.
|
||||||
|
For compatibility, #define sched_priority to itself, and #define
|
||||||
|
__sched_priority as sched_priority.
|
||||||
|
* posix/bits/cpu-set.h: New file containing, verbatim, the code
|
||||||
|
that was under #ifndef __cpu_set_t_defined in
|
||||||
|
sysdeps/unix/sysv/linux/bits/sched.h.
|

* include/bits/cpu-set.h: New wrapper.
