[PATCH 00/10] Fix various inconsistencies

[PATCH 00/10] Fix various inconsistencies

[Rasmus Villemoes]

With the help of a perl script (which will be sent separately once
it's no longer as embarrassing as it is currently), I checked the
man2-pages for consistency with the actual installed headers.

Rasmus Villemoes (10):
  Fix return type of readlinkat()
  Fix prototype for stime()
  Fix prototypes for semop() and semtimedop()
  Fix prototypes for [sg]etpriority()
  Fix prototype for sched_setaffinity()
  Add <sys/types.h> to synopsis of get_robust_list()
  Fix prototype for mbind(2)
  Add <signal.h> to synopsis for ppoll()
  Fix prototype for set_mempolicy(2)
  Fix prototype for syscall(2)

Well, at least <numaif.h> says nmask is const. The current kernel does
not define it as a const argument, but sys_mbind() only passes it to
get_nodes(), which does treat it as const.

Great stuff, Rasmus. Who knows, that script might be handy again 
one day, if you want to polish it up.

All of the patches look correct to me, and I've applied.
In a few cases, the errors came about because glibc
has changed the prototypes (in the distant past).

Thanks for the patches!

Cheers,

Michael

Looks like the semop() prototype changed between glibc 2.1 and 2.2.
(The semtimedop() prototype was always "size_t". Probably, 
I cut-pasted...)

Applied!
