reclaimed nodes hanging until all their children have been reclaimed
and then reclaim everything we can as far up to root as possible.
This is because the file system structures are currently interlinked
in a fashion which would make dotdot lookup based on purely a path
instead of a in-memory node parent member pointer very difficult.
Yes, this deserves a closer look some day.
directory entries already in readdir and caches the results instead
of waiting for each individial getattr from the kernel. For
high-latency links the difference in "ls -l" is quite astounding
and even on my lan "ls -lR" is faster than for nfs in a normal
directory hierarchy (i.e. not one artifically setup to have thousands
of files per directory).
TODO: implement some sort of bandwidth/latency measurement in the
code and enable or disable this option based on than information
(and a command-line flag).
should make this work with the IETF standard some day, also.
* kludge with writes and permissions a bit to be able to flush data
cached in ubc to files which are already with r/o permissions in
the backend
