Subject: Implement sys_rt_tgsigqueueinfo syscall decoder
X-Git-Tag: v4.7~109
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=297632be5cfba5d51fc027e518ad91cb40e71d0b;p=strace

Implement sys_rt_tgsigqueueinfo syscall decoder

* linux/dummy.h (sys_rt_tgsigqueueinfo): Remove.
* linux/syscall.h (sys_rt_tgsigqueueinfo): New prototype.
* signal.c (print_sigqueueinfo): New function, based on
sys_rt_sigqueueinfo.
(sys_rt_sigqueueinfo): Use print_sigqueueinfo.
(sys_rt_tgsigqueueinfo): New function.
