Liu Hua f5dec056ad uffd: Disable image deduplication after fork 
After a fork, both the child and parent processes may trigger a page fault (#PF)
at the same virtual address, referencing the same position in the page image.
If deduplication is enabled, the last process to trigger the page fault will fail.

Therefore, deduplication should be disabled after a fork to prevent this issue.
