NFS partial writes

NFS partial writes

[Kenny Simpson]

Hi, in nfs_writepage_sync in fs/nfs/write.c I see:

  result = NFS_PROTO(inode)->write(inode, cred,
&fattr, flags,
                                   offset, wsize,
page, &verf);

  if (result < 0) {
          /* Must mark the page invalid after I/O
error */
          ClearPageUptodate(page);
          goto io_error;
  }
  if (result != wsize)
          printk("NFS: short write, wsize=%u,
result=%d\n",
          wsize, result);
  refresh = 1;
  buffer  += wsize;
  base    += wsize;
  offset  += wsize;
  written += wsize;
  count   -= wsize;


Shouldn't buffer, base, offset, written, and count be
(inc|dec)remented by result instead of wsize?

This is with the latest CVS version of 2.5, but the
identical code is in Red Hat's 2.4.20-20.9.
