Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Al Viro says: ==================== netdev-related stuff in vfs.git There are several commits sitting in vfs.git that probably ought to go in via net-next.git. First of all, there's merge with vfs.git#iocb - that's Christoph's aio rework, which has triggered conflicts with the ->sendmsg() and ->recvmsg() patches a while ago. It's not so much Christoph's stuff that ought to be in net-next, as (pretty simple) conflict resolution on merge. The next chunk is switch to {compat_,}import_iovec/import_single_range - new safer primitives for initializing iov_iter. The primitives themselves come from vfs/git#iov_iter (and they are used quite a lot in vfs part of queue), conversion of net/socket.c syscalls belongs in net-next, IMO. Next there's afs and rxrpc stuff from dhowells. And then there's sanitizing kernel_sendmsg et.al. + missing inlined helper for "how much data is left in msg->msg_iter" - this stuff is used in e.g. cifs stuff, but it belongs in net-next. That pile is pullable from git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git for-davem I'll post the individual patches in there in followups; could you take a look and tell if everything in there is OK with you? ==================== Signed-off-by: David S.
