Comment 5 yunmeng365524 2023-10-19 14:40:38 UTC

在016版本内部跟踪

Comment 6 yunhe123 alibaba_cloud_group

2023-11-10 14:08:49 UTC

内部跟踪已有分析结论：在开启bigalloc的情况下， fallocate 操作需要 offset|len 与 cluster_size(16K) 对齐，但目前xfstests本身代码不会主动读取磁盘的cluster_zie信息并以此调整合并区间；且测试本身就会对小块做操作，ext4-2-bigalloc下满足不了条件，所以这个case不适用于在ext4-2-bigalloc文件系统中执行，适配用例，关闭该bug。
