[PATCH] VSOCK: Split vm_sockets.h into kernel/uapi

From: Andy King
Date: Thu Mar 07 2013 - 10:30:29 EST


Split the vSockets header into kernel and UAPI parts. The former gets the bits
that used to be in __KERNEL__ guards, while the latter gets everything that is
user-visible. Tested by compiling vsock (+transport) and a simple user-mode
vSockets application.
