Subject: [PATCH 1/2] linux/kernel.h: use 'short' to define USHRT_MAX, SHRT_MAX, SHRT_MIN
Date: Sun,  3 Feb 2019 01:06:24 +0900	[thread overview]
Message-ID: <1549123585-13800-1-git-send-email-yamada.masahiro@socionext.com> (raw)

The log of commit 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.
