Description

I've been working on sparse read support in the kclient, and got something working today, only to notice that after truncating a file, I would often get back -EINVAL when trying to read it. The problem seems to be this in PrimaryLogPG::do_sparse_read() :

  if (op.extent.truncate_seq) {
    dout(0) << "sparse_read does not support truncation sequence " << dendl;
    return -EINVAL;
  }

Would it be possible to support sparse reads against objects that have a non-zero truncate_seq?
