That looks reasonable. We should give people some time to respond
though, and maybe also mention that in WHATSNEW.txt.

I wonder whether the patch would remove the inode limit or set it to
zero (no new inodes allowed). For example in the Linux driver, we always
set the dqb_valid to QIF_LIMITS, which is (QIF_BLIMITS | QIF_ILIMITS),
so if I understand the docs, it means "set the inode quota to zero
inodes". Haven't tested though...

Thanks,
Uri.
