There are several failures while running xfstests-bld(generic/075 and 091). (reported by Ted) COLLAPSE RANGE issue are mixed with ZERO RANGE issue as per format and mount options. First, list up issues like the following. 1. format with 1KB or 2KB block size.(075, 091 are failed, COLLAPSE RANGE issue). 2. mount -o dioread_nolock. (091 is failed, ZERO RANGE issue.) - As I know, Lukas is checking this issue. 3. mount -o data=journal. (091 is failed, ZERO RANGE issue.) 4. format with bigalloc. (075 and 091 are failed, COLLAPSE RANGE issue). - Once I would like to be disable COLLAPSE RANGE on ext4 with bigalloc feature till finding the root-cause. first, I need the time to understand bigalloc feature.. 5. testing more.
