Test that we can get all extent/hole information for files with more than 16 extents and 15 holes which require a reallocation based on XFS_IOC_FSGETXATTR. Based on a testcase from Tomasz Majkowski <moosh009@gmail.com>. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Eric Sandeen <sandeen@sandeen.net>
