Hello,
After applied the 3.14-rt1 patch set, one compiling error occurred.
Compile failed with the default arch/x86/configs/x86_64_defconfig on my
laptop(Intel(R) Core(TM) i5-3230M CPU).
The configure command is 'make defconfig'.
Error messages:
linux-3.14/kernel/softirq.c: In function ‘__local_bh_enable_ip’:
linux-3.14/kernel/softirq.c:328:2: error: implicit declaration of fu
nction ‘preempt_check_resched’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
The reason is when configured with 'CONFIG_PREEMPT_VOLUNTARY', the
compiler can not find the definiation of function preempt_check_resched.
This patch is supplied to fix this problem.
