Hi Kent,

one quick question about the roadmap at this point: As far as I
understand bcachefs basically integrates bcache features directly in the
filesystem. So does this deprecate bcache itself in your opinion? Bcache
is obviously still useful for other FS, but I just want to know how
things will get maintained in the future.

I wanted to suggest / possibly start implementing bcache support for the
debian installer - obviously that only makes sense if I can expect it to
be in the mainline kernel for the foreseeable future :-).

Thanks,
