[LTP] About the diotest4 failure on linux kernel 5.15

[粟航(Bryce)]

Hello,I ported ltp to Android for testing. The diotest4 test on the Linux kernel 5.15 device failed. The file system was corrected when the test was run to test3. The correct values were passed to the next layer. How can I solve this problem? The same problem does not occur in other linux kernel versions.
The following are logs, and the related traces in extra file.
