Version 11 splits the changes in read-cache.c into 3 commits so that they can be independently evaluated. And adds subscript guard for istate->cache_nr > 0 which might be necessary if remove_index_entry_at() deletes the only entry in the array.

Jeff Hostetler (5):
  read-cache: add strcmp_offset function
  p0006-read-tree-checkout: perf test to time read-tree
  read-cache: speed up add_index_entry during checkout
  read-cache: speed up has_dir_name (part 1)
  read-cache: speed up has_dir_name (part 2)
