Hello,
Which is the I/O scheduler used by FBSD 5.4 ?
I googled in various ways but could not get an answer.
I do not have access to the source code.
TIA.
Sincere regards,
Pranav.J.Peshwe

it is called FCFSUSIIABPIWCTTOIS, which stands for
First Come First Serve Unless Someone Is In A Better Position
In Which Case The Temporal Order Is Subverted
also known as the standard one-way elevator taught in all operating
system courses.

http://www.freebsd.org/cgi/cvsweb.cgi/
ready for your perusal.

Thank you very much for the name and the source
link.Is there any documentation available on this
topic(fbsd io schedulers) ?
Where is the io scheduler located in the
src code tree ?
--
I found one more source for browsing the sources.
http://fxr.watson.org/

TIA.
Sincere regards,
Pranav

Your best bet is probably to mail the patch in a followup to the PR so that it
doesn't get lost.
