NTFS - list of things to do in no particular order:
- handle Unicode chars more inteligently - currently only iso-8859-1
chars are supported, it should be possible to get the filename
converted into koi-8, iso-8859-2 & utf-8 at least - there is
some Unicode support present under FreeBSD, would be worth considering
for adoption (it's needed to properly support Juliet CDs anyway)

* not very hard
- better support for writing; tricky is crash recovery
- cleanup the mess with several *readattr*() functions if possible
- avoid allocation temporary buffer to hold result of read()/data
to be written in ntfs_read() & ntfs_write() - besides being
unefficient, the user is able to panic the kernel with simple
open()/lseek()/read() sequence.
(from Chuq)
* finishing testing, even gained about 3-5% performance improvement
for simple cat file >/dev/null test
- ntfs_ntvattrget(): find out if it's worth the efford to use some hashing
for the list of ntnodes, so that it's not all scanned each time; it would
be fine to migrate the found ntnode towards the start of the list too;
the list search code is duplicated on two places, eliminate the duplicity
somehow
- convert the code to do caching in buffer cache indexed by
file-vnode/file-offset so that NTFS would take advantage of UBC;
it should also improve performance somewhat, because if it's necessary
to find some offset in a file, it's possible to check if the data
are available in the cache before doing the bmap operation first

- working VOP_BALLOC()
(from Chuq)
- add pathconf(2) support
(from Klaus Klein)
- make ntfs exportable, for the completeness sake
