Merge branch 'work.sock_recvmsg' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull kern_recvmsg reduction from Al Viro: "kernel_recvmsg() is a set_fs()-using wrapper for sock_recvmsg(). In all but one case that is not needed - use of ITER_KVEC for ->msg_iter takes care of the data and does not care about set_fs(). The only exception is svc_udp_recvfrom() where we want cmsg to be store into kernel object; everything else can just use sock_recvmsg() and be done with that. A followup converting svc_udp_recvfrom() away from set_fs() (and killing kernel_recvmsg() off) is *NOT* in here - I'd like to hear what netdev folks think of the approach proposed in that followup)" * 'work.sock_recvmsg' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: tipc: switch to sock_recvmsg() smc: switch to sock_recvmsg() ipvs: switch to sock_recvmsg() mISDN: switch to sock_recvmsg() drbd: switch to sock_recvmsg() lustre lnet_sock_read(): switch to sock_recvmsg() cfs2: switch to sock_recvmsg() ncpfs: switch to sock_recvmsg() dlm: switch to sock_recvmsg() svc_recvfrom(): switch to sock_recvmsg()
