Hi Ted,

You are right, thanks for taking a look. I did rebase the series, but I
posted the follow-up as a new thread rather than replying here, so it was
easy to miss. Sorry about that.

v3 is here:

https://lore.kernel.org/linux-ext4/20260722005922epcms2p566d8027c8d1dbb8d9c46e3d3b35b6fd0@epcms2p5/

It is based on dev at c143957520c6 and applies and builds cleanly there.
Li Chen's snapshot work replaced the commit path the old series was
patching, so it is a re-implementation on top of his work rather than a
plain rebase. The on-disk format is unchanged.

Thanks,
Daejun
