[PATCH 3/4] signal: Remove specific_send_sig_info

From: Eric W. Biederman
Date: Sun Sep 16 2018 - 14:06:32 EST



This function is static and it only has two callers. As
specific_send_sig_info is only called twice remembering what
specific_send_sig_info does when reading the code is difficutl and it
makes it hard to see which sending sending functions are equivalent to
which others.

So remove specific_send_sig_info to make the code easier to read.
