Subject: net: use SYSCALL_DEFINEx for sys_recv
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b7c0ddf5f270b2a3c0af326cb300eb17175d58e3;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

net: use SYSCALL_DEFINEx for sys_recv

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.
