This test creates some files, runs defrag on them, and compares the before/after fragmentation as well as file md5sums and timestamps. The test currently expects to find e4defrag in /usr/bin It should be relatively easy to add more interestingly fragmented files to the tests, as well as to test that memory-mapped files aren't touched, etc - but this gives us a framework. V2: remount before checking file contents, and create common.defrag. Signed-off-by: Eric Sandeen <sandeen@sandeen.net> Reviewed-by: Christoph Hellwig <hch@lst.de>
