[PATCH v2 0/2] name-hash: fix buffer overrun

From: Jeff Hostetler <jeffhost@microsoft.com>

Version 2 of this fix smashes the HT and chmod issues in the test code discussed on the mailing list. The test has also been updated to skip on 1 cpu systems.

================ Fix buffer overrun in handle_range_dir() when the final entry in the index was the only file in the last directory, such as "a/b/foo.txt". The look ahead (k_start + 1) was invalid since (k_start + 1) == k_end.
