From 2dc0e68d5ada6d29554c760bee498c2612530d12 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 7 Mar 2019 16:27:11 -0800 Subject: [PATCH] linux/kernel.h: use 'short' to define USHRT_MAX, SHRT_MAX, SHRT_MIN The commit log of 44f564a4bf6a ("ipc: add definitions of USHORT_MAX and others") did not explain why it used (s16) and (u16) instead of (short) and (unsigned short). Let's use (short) and (unsigned short), which is more sensible, and more consistent with the other MAX/MIN defines. As you see in include/uapi/asm-generic/int-ll64.h, s16/u16 are typedef'ed as signed/unsigned short. So, this commit does not have a functional change. Remove the unneeded parentheses around ~0U while we are here.
