SubjectRe: [RFC patch 0/3] signals: add rt_tgsigqueueinfo syscall
Date
The core of this looks fine to me.  Presumably this would be expressed in
userland as pthread_sigqueue.

You are missing compat_sys_rt_tgsigqueueinfo for e.g. the
arch/x86/ia32/ia32entry.S table.

The clean way to do that would be a do_rt_tgsigqueueinfo taking
the siginfo_t * (not __user). That is, just split out the copy_from_user,
so compat_sys_rt_tgsigqueueinfo does copy_siginfo_from_user32 instead.


Thanks,
Roland
