The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.

193ccd2d90 Improve write throttling by doing it on page-size basis. The `standard' 
solution would cut up files unnessisary during allocation. It also made
assumptions about ucb wich were propably right but still.

9609b0ed76 Implement session closure on sequential media when requested on mount. It will 
allow CD-ROM/DVD-ROM/DB-ROM drives to read the media while still allowing them
to be appended later. It can also be seen as a way to make mountable
snapshots.

2ac9ba8c48 If mounting for read-write dont allow a session number to be specified since 
its currently still misbehaving. If supported later, it would allow one or a
series of sessions on a sequential recordable media to be ignored as if they
never were created.

Also fix a small comment: its not the direct but the bootstrap disc strategy
that we close down.

writable tracks on session opening. Note that this an optionally implemented
feature and thus no error will be generated if it fails; the drive will most
likely autorepair it.

81723cc93e The great QUOTA purge of '08: get rid of those #ifdef QUOTA and

9b08c3c516 Two fold commit: 
1) Enhance write speed significantly on RMW media like CD-RW, DVD-RW but also
on the DVD+RW and all other ECC blocked media. Significant speedups of access
to the device for say compilation on the DVD. Streaming copy is also still at
maximum speed though vast amounts of directory copy work can show side effects
that appear it to slow down but are actually logical when you consider that
most small files are embedded into the descriptors itself.

2) explicit wait for the created RMW thread to spinup

df11d3f1f5 Allow for the exclusive selection of `direct' for rdonly mounts; its disabled 
for now since its a lot slower than `rmw' access.

For archs that have trouble with `rmw' for whatever reason can so use it as a
scapegoat to allways mount savely rdonly though slower.

a287d23dee Rewrite allocation scheme's determination and implementation replacing the

5e89a5a8f1 Fixup important bug in internal recorded data fixup. Although most unlikely 
it could result in theory result in descriptor trashing.

On the performance side, it would try to fixup *every* descriptor even if
it wasn't an internally allocated one. Performance loss wasn't that big but
every bit helps.
