This patch aims to add more tests to the xfstest suite to check whether the target file system recovers correctly after a crash. These test cases are generated by CrashMonkey, a crash-consistency testing framework built at the SASLab at UT Austin. This patch batches 37 crash-consistency tests into a xfstest test, each of which checks the hard link behavior under different scenarios. This test creates hard-links between files in the same directory or across directories, while allowing fsync of either the files involved, their parent directories, or unrelated sibling files. After each sub test, the metadata of the persisted file is checked for the correct link count. Additionally, each sub test is followed by fsck to check for inconsistencies. The tests run on a 256MB file system, and the working directory is cleaned up after every sub test.
