sigprocmask.2: s/kernel_sigset_t/sigset_t/

["Alejandro Colomar (man-pages)" <alx.manpages@gmail.com>]

Hi Michael,

AFAICT, the syscalls [rt_]sigprocmask use '[old_]sigset_t' (there's the
'__user' modifier too), so 'kernel_' should be removed from the types,
shouldn't it?

Thanks,

Alex

SYNOPSIS
       #include <signal.h>

       /* Prototype for the glibc wrapper function */
       int sigprocmask(int how, const sigset_t *restrict set,
                       sigset_t *restrict oldset);

       /* Prototype for the underlying system call */
       int rt_sigprocmask(int how, const kernel_sigset_t *set,
                       kernel_sigset_t *oldset, size_t sigsetsize);

       /* Prototype for the legacy system call (deprecated) */
       int sigprocmask(int how, const old_kernel_sigset_t *set,
                       old_kernel_sigset_t *oldset);
