I don't think so, the problem is kernel and btrfs-progs all need to modify extent buffer, which make the read time conversion become a burden in write path. > >> Thus only the following 5 patches need extra review attention: >> - Patch 0017 >> - Patch 0018 >> - Patch 0022 >> - Patch 0023 >> - Patch 0024 > > Anyway, this patch series does not apply cleanly on u-boot/master.

That's strange, the branch is originally based on an older master, as you can find in the github. I guess there are some more btrfs related code change since then, I'll rebase them to latest master, and update the github repo then. Thanks, Qu > > Marek >
