During NFSv2 and NFSv3 READDIR/PLUS operations, NFSD advances rq_next_page to the full size of the client-requested buffer, then releases all those pages at the end of the request. The next request to use that nfsd thread has to refill the pages. NFSD does this even when the dirlist in the reply is small. With NFSv3 clients that send READDIR operations with large buffer sizes, that can be 256 put_page/alloc_page pairs per READDIR request, even though those pages often remain unused. We can save some work by not releasing dirlist buffer pages that were not used to form the READDIR Reply. I've left the NFSv2 code alone since there are never more than three pages involved in an NFSv2 READDIR Reply. Eventually we should nail down why these pages need to be released at all in order to avoid allocating and releasing pages unnecessarily. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

The benefit of the xdr_stream helpers is that they transparently handle encoding an XDR data item that crosses page boundaries. Most of the open-coded logic to do that here can be eliminated. A sub-buffer and sub-stream are set up as a sink buffer for the directory entry encoder. As an entry is encoded, it is added to the end of the content in this buffer/stream. The total length of the directory list is tracked in the buffer's @len field. When it comes time to encode the Reply, the sub-buffer is merged into rq_res's page array at the correct place using xdr_write_pages(). Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

Also, clean up: Rename the encoder function to match the name of the result structure in RFC 1813, consistent with other encoder function names in nfs3xdr.c. "diropres" is an NFSv2 thingie. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

As an additional clean up, some renaming is done to more closely reflect the data type and variable names used in the NFSv3 XDR definition provided in RFC 1813. "attrstat" is an NFSv2 thingie. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

NFSD initializes an encode xdr_stream only after the RPC layer has already inserted the RPC Reply header. Thus it behaves differently than xdr_init_encode does, which assumes the passed-in xdr_buf is entirely devoid of content. nfs4proc.c has this server-side stream initialization helper, but it is visible only to the NFSv4 code. Move this helper to a place that can be accessed by NFSv2 and NFSv3 server XDR functions. Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

Pull io_uring followup fixes from Jens Axboe: - The SIGSTOP change from Eric, so we properly ignore that for PF_IO_WORKER threads. - Disallow sending signals to PF_IO_WORKER threads in general, we're not interested in having them funnel back to the io_uring owning task. - Stable fix from Stefan, ensuring we properly break links for short send/sendmsg recv/recvmsg if MSG_WAITALL is set. - Catch and loop when needing to run task_work before a PF_IO_WORKER threads goes to sleep. * tag 'io_uring-5.12-2021-03-21' of git://git.kernel.dk/linux-block: io_uring: call req_set_fail_links() on short send[msg]()/recv[msg]() with MSG_WAITALL io-wq: ensure task is running before processing task_work signal: don't allow STOP on PF_IO_WORKER threads signal: don't allow sending any signals to PF_IO_WORKER threads
