The test case was still running at that time. Near the end > of the full file, I find "Iteration 13". It looks like the test case is not > hanging, but just taking long time to complete the 20 iterations. 778 invokes xfs_io and fallocate a few tens of thousands of times, which makes the test runtime really slow if fork/exec() aren't fast. I try to fix that here: https://lore.kernel.org/fstests/176279908967.605950.2192923313361120314.stgit@frogsfrogsfrogs/T/#t As well as reducing the test file size for 774, per everyone's comments. --D
