The limit is based on the blocksize; but this test seems to assume an absolute count of the number of acl entries, and looking at the xfs max code, it looks like if we just wired it up to some arbitrary number, such as "32", it would probably allow ext4 to run the test and pass it correctly. I'm not sure it's would test something useful that's not tested by the other xfstests, though. - Ted
