I/O scheduler (aka dsched)

[Alex Hornung]

:     Have you done any testing against typically expensive HAMMER
: operations
:     such as rm -rf's and tar extractions?

No, I haven't done any of those; it would be helpful if someone could
provide me with some details on how to do some benchmarking on that; i.e. on
which commands to run in parallel.

Also, please note all that the patch I attached to the previous email
shouldn't really be used anymore. If you want to try dsched and dsched_fq,
please fetch from my iosched-current branch on leaf. This is what I really
keep updated and where you'll find future improvements.

Cheers,
Alex Hornung
