      [PATCH] Make VT8653 work with AGP · 4327a6d9
      Rob Weryk authored
      This makes VT8653 (VIA Apollo Pro266T) work with AGP.  I had someone
      test it and verify it works.

      [PATCH] Update powermac IDE driver · 056cc252
      Paul Mackerras authored
      This updates the powermac IDE driver in 2.5 so it uses the 2.5 kernel
      interfaces and types rather than the 2.4 ones.  It also makes it use
      blk_rq_map_sg rather than its own code to set up scatter/gather lists in
      pmac_ide_build_sglist, and makes it use ide_lock instead of
      io_request_lock.

      [PATCH] Update macserial driver · 594c9846
      Paul Mackerras authored
      This updates the macserial driver in 2.5 so it compiles and works.  The
      main changes are to use schedule_work instead of task queues and BHs.
      The patch also removes the wait_key method.
      
      I know we need to change macserial to use the new serial
      infrastructure.  I'm posting this patch in case it is useful to anyone
      trying to compile up a kernel for a powermac at the moment.

      [PATCH] kNFSd: Make sure svc_process releases response even on error. · aeb673ca
      Neil Brown authored
      If a rpc operation indicates that response should
      be dropped (e.g. kmalloc failure) we must still
      call pc_release to release anything it may have allocated.

      [PATCH] kNFSd: Convert readlink to use a separate page for returning symlink contents. · 3a689637
      Neil Brown authored
      This allows NFSv3 to manage 4096byte symlinks.
      
      Also remove now-unused svcbuf_reserver function.
      
      This was used to reserve space in output buffer
      for 'data', but now this is stored in separate page.

      [PATCH] kNFSd: Make sure final xdr_buf.len is correct on server reply · 65774d49
      Neil Brown authored
      rq_res->len was not always updated properly.
      It is only needed in the sendto routine, so we calculate
      it just before that is called, and don't bother
      updating it anywhere else.

      [PATCH] kNFSd: Support zero-copy read for NFSD · 835a922a
      Neil Brown authored
      From Hirokazu Takahashi <taka@valinux.co.jp>
      
      This patch changes read and readdir in nfsd.
      
      read:
        If the file supports readpage, we use it to collect pages out of the page
        cache and to attache them directly to the outgoing nfs reply.
        The reduces the number of copies by one, and if the filesystem/device
        driver didn't copy the data, and if the network card can support not copying
        the data, then you get zero-copy reads.
      
      readdir:
        A separate page is used for stoing the readdir response so that a fill
        PAGE_SIZE bytes of reply can be supported.

      [PATCH] kNFSd: Use ->sendpage to send nfsd (and lockd) replies. · 032d3607
      Neil Brown authored
      From Hirokazu Takahashi <taka@valinux.co.jp>
      
      As all rpc server replies are now in well defined pages,
      we can use ->sendpage to send these replies, and so
      make use for zero-copy transmit on network cards that
      support it.

      [PATCH] md: Fix another two bug in raid5 · 571f3078
      Neil Brown authored
       A partial block write over a block on a failed device
       would need to pre-read that block, which means pre-read all
       blocks in stripe and generate that block.  But the generate-block
       code never checked for this possibility, so it wouldn't happen.

      [PATCH] md: Fix bug in raid5 · a531b8fc
      Neil Brown authored
      When analysing a stripe in handle_stripe we set bits
       R5_Wantread or R5_Wantwrite
      to indicate if a read or write is needed.  We don't actually schedule the
      IO immediately as this is done under a spinlock (sh->lock) and
      generic_make_request can block.  Instead we check these bits after
      the lock has been lifted and then schedule the IO.
      
      But once the lock has been lifted we aren't safe against multiple
      access, and it is possible that the IO will be scheduled never, or twice.
      
      So, we use test_and_clear to check and potentially schedule the IO.
      
      This wasn't a problem in 2.4 because the equivalent information was
      stored on the stack instead of in the stripe.
      
      We also make sure bi_io_vec[0] has correct values as a previous
      call to generic_make_request may have changed them.

      [PATCH] md: Fix assorted raid1 problems. · 81fc1e93
      Neil Brown authored
      From Angus Sawyer <angus.sawyer@dsl.pipex.com>:
      
      1. Null pointer dereference in end_sync_read
      
         r1_bio->read_disk is not initialised correctly in sync_request .
      
         this is used in end_sync_read to reference the structure
         conf->mirror[read_disk].rdev which with one disk missing is NULL.
      
      
      2. Null pointer dereference in mempool_free()
      
         This is a race between close_sync() conf->r1_bufpool =3D NULL and put_buf()
         mempool_free().
      
         bio completion -> resume_device -> put_buf -> mempool_free(r1_bufpool)
      				|
      			   [ wakeup]
      				|
      			   close_sync()	-> r1_bufpool = NULL;
      
         The patch attached  reorders the mempool_free before the  barrier is released
         and merges resume_device() into put_buf(), (they are only used together).
         Otherwise I have kept the locking and wakeups identical to the existing code.
         (maybe this could be streamlined)
      
      3.  BUG() at close_sync() if (waitqueue_active(&conf->wait_resume).
      
         This occurs with and without the patch for (2).
      
         I think this is a false BUG().  From what I understand of the device barrier
         code, there is nothing wrong with make_request() waiting on wait_resume when
         this test is made.  Therefore I have removed it (the wait_idle test is still
         correct).
      
      4. raid1 tries to start a resync if there is only one working drive,
         which is pretty pointless, and noisy.  We notice that special case and
         avoid the resync.

      [PATCH] md: Misc little raid fixes · eddcaa28
      Neil Brown authored
      Roughly in order of patch:
      
      1/ xor.h is never needed in md.c
      2/ set sb_loaded when we 'sync' mddev to rdev as well as when we load
         sb into rdev from disk.
      2/ due to lifetime changes, active count can be 2 when we stop array
      3/ due to lifetime changes, we need to explicitly clear the ->pers when we
         stop an array
      4/ autostart can only work for 0.90.0 superblocks.
         None others would be silly enough to store device numbers for
         all devices in the superblock...
      5/ we had lost the setting of 'sb' when auto-starting an array.
      6/ Code currently calls export_rdev(start_rdev) when
         IS_ERR(start_rdev), which causes an oops.
      7/ /proc/mdstat contents error:
             code does not take into account that delayed
             resyncs can wait with curr_resync = 1 or 2.
      8/ There is a premature "return NOTIFY_DONE", that possibly was in
         for debugging once...

      Stephen Lord authored
      the layout of a log record for a buffer, the linux code deals with buffers
      which are not contiguous in memory - this only applies to an inode buffer.
      This adds one more fragmentation case to the code, and a line was missing
      from this. The end result would be the logging of too much data if this
      was not the last component of the buffer.
      
      The code was definitely wrong, but I think the chances of hitting this were
      pretty slim, and the resulting error would only matter if there was a
      crash shortly afterward.
