Creation of $testfile fails when using a multi-block directory test configuration because, 1. A directory can have a pseudo maximum extent count of 10. 2. In the worst case a directory entry creation operation can consume (XFS_DA_NODE_MAXDEPTH + 1 + 1) * (Nr fs blocks in a single directory block) extents. With 1k fs block size and 4k directory block size, this evaluates to, (5 + 1 + 1) * 4 = 7 * 4 = 28 > 10 (Pseudo maximum inode extent count). This commit fixes the issue by creating $testfile before injecting reduce_max_iextents error tag. Reported-by: Darrick J. Wong Suggested-by: Darrick J.
