Subject: cluster/distribute: detect stale layouts in entry fops

dht_mkdir ()
{
      first-hashed-subvol = hashed-subvol for "bname" in in-memory
                            layout of "parent";
      inodelk (SETLKW, parent, "LAYOUT_HEAL_DOMAIN", "can be any
               subvol, but we choose first-hashed-subvol randomly");
      {
begin:
            hashed-subvol = hashed-subvol for "bname" in in-memory
                            layout of "parent";
            hash-range = extract hashe-range from layout of "parent";

            ret = mkdir (parent/bname, hashed-subvol, hash-range);
            if (ret == "hash-value doesn't fall into layout stored on
                       the brick (this error is returned by posix-mkdir)")
            {
                refresh_parent_layout ();
                goto begin;
            }

      }
      inodelk (UNLCK, parent, "LAYOUT_HEAL_DOMAIN",
               "first-hashed-subvol");

      proceed with other parts of dht_mkdir;
}

posix_mkdir (parent/bname, client-hash-range)
{

       disk-hash-range = getxattr (parent, "dht-layout-key");
       if (disk-hash-range != client-hash-range) {
              fail-with-error ("hash-value doesn't fall into layout
                                stored on the brick");
              return 0;
       }

       continue-with-posix-mkdir;
}

Similar changes need to be done for dentry operations like create,
symlink, link, unlink, rmdir, rename. These will be addressed in
subsequent patches. This patch addresses only mkdir codepath.

This change breaks stripe tests, as on some striped subvols dht layout
xattrs are not set for some reason. This results in failure of
mkdir. Since striped volumes are always created with dht, some tests
associated with stripe also fail. So, I am making following tests
changes (since stripe is out of maintainance):
* modify ./tests/basic/rpc-coverage.t to not to use striped volumes
* mark all (2) tests in tests/bugs/stripe/ as bad tests
