[PATCH v12 0/5] read-cache: speed up add_index_entry

From: Jeff Hostetler <jeffhost@microsoft.com>

Version 12 adds a new t/perf/repo/inflate-repo.sh script to let you inflate a test repo, such as a copy of git.git or linux.git, to have a branch containing a very large number of (non-synthetic) files.

It also fixes the "##" comments in the many-files.sh script as mentioned on the mailing list.

I've also updated the commit message on part 2 to show the results when run on an inflated copy of linux.git with 1M+ files.

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)
