From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- ANDROID_3.4.5/include/net/inet_sock.h | 253 ---------------------------------- 1 file changed, 253 deletions(-) delete mode 100644 ANDROID_3.4.5/include/net/inet_sock.h (limited to 'ANDROID_3.4.5/include/net/inet_sock.h') diff --git a/ANDROID_3.4.5/include/net/inet_sock.h b/ANDROID_3.4.5/include/net/inet_sock.h deleted file mode 100644 index ae17e135..00000000 --- a/ANDROID_3.4.5/include/net/inet_sock.h +++ /dev/null @@ -1,253 +0,0 @@ -/* - * INET An implementation of the TCP/IP protocol suite for the LINUX - * operating system.
