I think you're the 4th person to propose this patch. Here are the three
prior postings:

    https://lore.kernel.org/ceph-devel/1577111958-100981-1-git-send-email-chenwandun@xxxxxxxxxx/
    https://lore.kernel.org/ceph-devel/1612165930-110076-1-git-send-email-jiapeng.chong@xxxxxxxxxxxxxxxxx/
    https://lore.kernel.org/ceph-devel/20211221143614.480385-1-deng.changcheng@xxxxxxxxxx/

It's not as simple as doing a 1:1 conversion like this. Please look at
the threads above and offer a revised patch or let us know whether you
want us to drop this one.

Thanks,
