Subject: Re: CD-ROM Driver Design
There are already two file-systems for CD-audio on Linux :
- cdfs at
http://www.elis.rug.ac.be/~ronsse/cdfs/
- audiofs at
http://fly.cc.fer.hr/~ptolomei/audiofs/
Are you sure there is a need for a third one ? The audiofs uses the
CDROMREADAUDIO for reading the data and uses the page-cache for caching. I
personally added the page-cache code , but I don't believe it makes a lot
of sense, because when ripping audio, you read data sequentially , so the
cache just eats all free RAM ( possibly throwing out other more usefull
cached data ) and gives almost no gain. By the way , when there is a
"normal" FS on a "normal" block device, does the data get cached twice,
once in buffer-cache and once in page-cache ?
