From f26d456b98abf02b3ff92f1a3c0d4473b7ffd85c Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Thu, 23 Apr 2020 10:58:01 -0300 Subject: linux: Fix __NSIG_WORDS and add __NSIG_BYTES The __NSIG_WORDS value is based on minimum number of words to hold the maximum number of signals supported by the architecture. This patch also adds __NSIG_BYTES, which is the number of bytes required to represent the supported number of signals. It is used in syscalls which takes a sigset_t. Checked on x86_64-linux-gnu and i686-linux-gnu.
