I excluded the writeback tracepoints you mentioned writeback_mark_inode_dirty writeback_dirty_inode_start writeback_dirty_inode writeback_dirty_page writeback_write_inode and left all other writeback tracepoints enabled, also dropped xfs_file_buffered_write and xfs_file_fsync. This time I can reproduce generic/048 quickly and please download the trace info from below http://128.199.137.77/writeback-v2/ Thanks, Eryu -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
