Hmm, this seems like it might be a troublesome feature... Are we sure that there is proper kernel/tool compatibility for an extent-mapped journal? At least none of the Lustre code has any support for this, though they can handle the INCOMPAT_EXTENTS feature, and I don't think this was present in older kernels either. I haven't looked at the code for this yet, so it may be that it will "just work", but if this is a new feature I would urge caution w.r.t. compatibility before this is merged upstream (in either e2fsprogs or the kernel).
