how to fix [not run] xfs_io fzero failed (old kernel/wrong fs?)

Hi, everyone!

I met issues are as below:

generic/008      [not run] xfs_io fzero failed (old kernel/wrong fs?)
generic/009      [not run] xfs_io fzero failed (old kernel/wrong fs?)
generic/012      [not run] xfs_io fcollapse failed (old kernel/wrong

fs?)
generic/016 [not run] xfs_io fcollapse failed (old kernel/wrong
fs?)
generic/021 [not run] xfs_io fcollapse failed (old kernel/wrong
fs?)
generic/022 [not run] xfs_io fcollapse failed (old kernel/wrong
fs?)
generic/031 [not run] xfs_io fcollapse failed (old kernel/wrong
fs?)
generic/033 [not run] xfs_io fzero failed (old kernel/wrong fs?)
generic/058 [not run] xfs_io finsert failed (old kernel/wrong
fs?)
generic/060 [not run] xfs_io finsert failed (old kernel/wrong
fs?)
generic/061 [not run] xfs_io finsert failed (old kernel/wrong
fs?)
generic/064 [not run] xfs_io finsert failed (old kernel/wrong
fs?)
generic/072 [not run] xfs_io fcollapse failed (old kernel/wrong
fs?)

I read the code and retry to exec xfs_io:

The kernel is enough new and the fs seems right.
Could you help me?
