Yeah.  I would like to give priority to in-kernel code after this.
The in-kernel code in 2.6.30 is almost up to date.

At present, nilfs2-module 2.0.14 has a patch that is not included in
2.6.30.  But, it's exceptional.  I'm thinking that I first merge
updates to mainline and then backport them to the standalone package
for some time in the future.

I'll make an exception for bugfixes; they should be applied both tree
in parallel.

Yes, 2.6.30 includes some infuential changes as per usual.  I tried to
follow the changes, but soon gave up due to the change around mmap vfs
interface. (sigh)

Thanks,
