The patchesmade test 240 in the xfstests suite pass when it consistently did not for me without it. However I found that test 104 hung the two times I tried it. At first I thought it could have been just taking a long time but the fsstress processes were unkillable and shutdown didn't complete either. I tried again after removing the patches and 104 passed again. -Alex _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
