From cde227afe6b997dce08bcfc2aa6e373fb56857b0 Mon Sep 17 00:00:00 2001 From: "mao, bibo" Date: Tue, 11 Apr 2006 12:54:54 +0200 Subject: [PATCH] x86_64: inline function prefix with __always_inline in vsyscall In vsyscall function do_vgettimeofday(), some functions are declared as inlined, which is a hint for gcc to compile the function inlined but it not forced. Sometimes compiler does not compile the function as inlined, so here inline is replaced by __always_inline prefix. It does not happen in gcc compiler actually, but it possibly happens.
