1387  head = inode_hashtable + hash(sb, ino)
1389  again :
1390  spin_lock( & inode_hash_lock)
1391  inode = d_inode_fast is the fast path version of find_inode, see the comment at* iget_locked for details.
1392  spin_unlock( & inode_hash_lock)
1394  If inode Then
1395  If IS_ERR(inode) Then Return NULL
1397  writeback.h requires fs.h; it, too, is not included from here.
