Subject: [PATCH] net: use SYSCALL_DEFINEx for sys_recv
Date: Tue, 15 Apr 2014 15:50:01 +0200 [thread overview]
Message-ID: <1397569801-10485-1-git-send-email-jan.glauber@gmail.com> (raw)
Make sys_recv a first class citizen by using the SYSCALL_DEFINEx
macro. Besides being cleaner this will also generate meta data
for the system call so tracing tools like ftrace or LTTng can
resolve this system call.
