net: socket: add __sys_recvfrom() helper; remove in-kernel call to syscall
Using the net-internal helper __sys_recvfrom() allows us to avoid the internal calls to the sys_recvfrom() syscall. This patch is part of a series which removes in-kernel calls to syscalls. On this basis, the syscall entry path can be streamlined. For details, see http://lkml.kernel.org/r/20180325162527.GA17492@light.dominikbrodowski.net Cc: David S. Miller <davem@davemloft.net> Cc: netdev@vger.kernel.org Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
