This is a testcase for a bug which goes way back; googling "xfs_trans_log_inode NULL pointer dereference" yields sporadic reports over several years. The test sets up several two-extent files with speculative preallocation on them, and then runs xfs_fsr. The kernelside code ignores the preallocation, and therefore sets up the temporary inode incorrectly after the inode fork swap. It is a "dangerous" test because the extent mishandling on the temporary inode causes a null pointer dereference and oops when the inode's i_itemp pointer gets overwritten and we blow up in logging code that tries to use it.
