From 7cc05662682da4b0e0a4fdf3c3f190577803ae81 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 28 Jan 2015 18:04:53 +0100 Subject: [PATCH] net: remove sock_iocb The sock_iocb structure is allocate on stack for each read/write-like operation on sockets, and contains various fields of which only the embedded msghdr and sometimes a pointer to the scm_cookie is ever used. Get rid of the sock_iocb and put a msghdr directly on the stack and pass the scm_cookie explicitly to netlink_mmap_sendmsg. Signed-off-by: Christoph Hellwig Signed-off-by: David S.
