I'll probably throw that into #next.dcache - if nothing else,
that cuts down on the size of patch converting d_subdirs/d_child
from list to hlist...
Need to get some sleep first, though - only 5 hours today, so
I want to take another look at that thing tomorrow morning -
I don't trust my ability to spot obvious bugs right now... ;-/
Oh, well - that at least might finally push the old "kernel-side
rm -rf done right" pile of half-baked patches into more useful
state, probably superseding most of them.
