It seems that this is not caused by my patch set? And I can not duplicate in local.

If the backend is on the persistent memory, QEMU needs to take proper operations to ensure its writes persistent on the persistent memory. Otherwise, a host power failure may result in the loss the guest data on the persistent memory. This v3 patch series is based on Marcel's patch "mem: add share parameter to memory-backend-ram" [1] because of the changes in patch 1.

Changes in v4: * (Patch 2) Fix compilation errors found by patchew. Changes in v3: * (Patch 5) Add a is_pmem flag to ram_handle_compressed() and handle PMEM writes in it, so we don't need the _common function. * (Patch 6) Expose qemu_get_buffer_common so we can remove the unnecessary qemu_get_buffer_to_pmem wrapper. * (Patch 8) Add a is_pmem flag to xbzrle_decode_buffer() and handle PMEM writes in it, so we can remove the unnecessary xbzrle_decode_buffer_{common, to_pmem}. * Move libpmem stubs to stubs/pmem.c and fix the compilation failures of test-{xbzrle,vmstate}.c. Changes in v2: * (Patch 1) Use a flags parameter in file ram allocation functions. * (Patch 2) Add a new option 'pmem' to hostmem-file. * (Patch 3) Use libpmem to operate on the persistent memory, rather than re-implementing those operations in QEMU. * (Patch 5-8) Consider the write persistence in the migration path.
