Hi,
Thank You. How great. I am adding a built in queuing mechanism to your
system. The idea is to have the built in functionality so that as files are
created they are placed in a queue (implemented as a linked list); this
queue always returns the next file to be processed. It is intended to speed
up an existing application that resides in user space and dumps query files
on to a database for further processing.
In a lot of ways it doesn't necessarily make sense. It should be probably be
a part of the VFS, akin to all file systems. Or just left in user space. But
it is an Intern project and it is so very cool. I asked to build a small FS
from the ground-up -- so if I have success here I will be doing that this
summer.
I started poking into your namei.c file (reiserfs_add_entry) and I've been
having some good results. Everything will probably get moved into ioctl
later but I am still trying to figure things out.
Your code is nice,
Jenn

Are queues directories? Are you doing it for V4 (strongly
recommended)? Others need this functonality....

That would be an ideal implementation. Yes.
Thanks,

Well I'd be happy to accept a directory plugin for reiser4 with LIFO and
FIFO queueing implemented using readdir ordering of directory contents.

Me too. ; )
But I imagine I could easily get that incorporated into my project. That
would be an interesting pursuit. They are pretty flexible at the Lab. And it
is always nice to work on something that is truly useful.
