Commit Message

Allison Henderson Sept. 26, 2018, 10:28 a.m. UTC 
This patch adds three new tests parent pointer operations.
The first test includes simple operations including link, unlink,
rename, and overwrite.  The second test exercises hardlinks and
muliple parent pointers.  The last test exercises the error inject
and recovery.
