Below is one response to a similar question from the l-k archive: From: David Balazic <[EMAIL PROTECTED]> Date: Thu, 13 Jan 2000 12:08:39 -0800 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 ?
