One thing I have considered doing if I got a large amount of spare time (IE something that'll never happen) is to investigate getting the user-mode-linux code and taking the block IO part to make file systems run in user-space as a database interface. For something like a large squid box it might get a performance gain to have small operations (directory lookups) take place in user-land rather than have a system call for each one. Also it could potentially have some benefits for debugging. I thought that combining the above with a LD_PRELOAD library to take over the read/write/open/etc library calls could allow an application to think it's using regular files while it's really accessing a user-land process and talking over named pipes. Then you could test out a new version of a file system without risking crashing your machine! -- http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/projects.html Projects I am working on http://www.coker.com.au/~russell/ My home page
[reiserfs-list] reiserfs-raw
ReiserFS developers: What is the status of the reiserfs-raw branch? Is it still being maintained, or has it been completely postponed awaiting finding space/resources/time for a more generic filesystem interface mechanism for such applications? The last known release of reiserfs-raw is 2.4.0-test10-reiserfs-raw, but this patch contains many things not actually part of the reiserfs-raw changes (i.e. the whole of reiserfs, AIO, hotswap capabilities, and from what it seems a bunch of more or less unrelated patches), with no references to which versions these are based on, making it increasingly hard to maintain such a kernel. It would be a shame to let all this work go down the drain I think. -- Henrik Nordstrom Squid Developer

I agree that it is a shame to let it go to waste, but better to leave behind a sponsor who can't understand that deep work normally takes 9 months at least. Version 4 will be exciting. Hans

True. It was a bit rushed then, but it did manage to successully complete a cache backeoff... -- Henrik Nordstrom Squid developer
