Christoph, Darrick, Shiyang, I'm losing my nerve to try to jam this into v5.16 this late in the cycle. I do want to get dax+reflink squared away as soon as possible, but that looks like something that needs to build on top of a v5.16-rc1 at this point. If Linus does a -rc8 then maybe it would have enough soak time, but otherwise I want to take the time to collect the acks and queue up some more follow-on cleanups to prepare for block-less-dax.

I do want to get dax+reflink squared away as soon as possible, but that looks like something that needs to build on top of a v5.16-rc1 at this point. If Linus does a -rc8 then maybe it would have enough soak time, but otherwise I want to take the time to collect the acks and queue up some more follow-on cleanups to prepare for block-less-dax.

Christoph, Darrick, Shiyang, I'm losing my nerve to try to jam this into v5.16 this late in the cycle. I do want to get dax+reflink squared away as soon as possible, but that looks like something that needs to build on top of a v5.16-rc1 at this point. If Linus does a -rc8 then maybe it would have enough soak time, but otherwise I want to take the time to collect the acks and queue up some more follow-on cleanups to prepare for block-less-dax. -- dm-devel mailing list dm-devel@redhat.com https://listman.redhat.com/mailman/listinfo/dm-devel
