Merge branch 'work.preadv2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull vfs cleanups from Al Viro: "More cleanups from Christoph" * 'work.preadv2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: nfsd: use RWF_SYNC fs: add RWF_DSYNC aand RWF_SYNC ceph: use generic_write_sync fs: simplify the generic_write_sync prototype fs: add IOCB_SYNC and IOCB_DSYNC direct-io: remove the offset argument to dio_complete direct-io: eliminate the offset argument to ->direct_IO xfs: eliminate the pos variable in xfs_file_dio_aio_write filemap: remove the pos argument to generic_file_direct_write filemap: remove pos variables in generic_file_read_iter
