Merge branch 'iov_iter' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull iov_iter updates from Al Viro: "More iov_iter work - missing counterpart of iov_iter_init() for bvec-backed ones and vfs_read_iter()/vfs_write_iter() - wrappers for sync calls of ->read_iter()/->write_iter()" * 'iov_iter' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: fs: add vfs_iter_{read,write} helpers new helper: iov_iter_bvec()
