NFS: Optimise append writes with holes If a file is being extended, and we're creating a hole, we might as well declare the entire page to be up to date. This patch significantly improves the write performance for sparse files in the case where lseek(SEEK_END) is used to append several non-contiguous writes at intervals of < PAGE_SIZE.
