From: Asias He Date: Thu, 25 Jul 2013 09:39:34 +0000 (+0800) Subject: VSOCK: Move af_vsock.h and vsock_addr.h to include/net X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=82a54d0ebbee03a8dcf4e1e4016a53fed4d6c933;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git VSOCK: Move af_vsock.h and vsock_addr.h to include/net This is useful for other VSOCK transport implemented outside the net/vmw_vsock/ directory to use these headers.
