Persistent module data

[sirpj@ecs.csus.edu]

Hi,

I signed up a while ago. Because I am working at LLNL as an Intern and
have been given a neat assignment that involves coding some extensions
to reiser. I am implementing a file queueing mechanism that maintains
files as they are written in FIFO order. When you call ioctl() the 'next
file' in the queue is returned.

I have the FIFO queue implemented as a linked list that keeps track of
the file names and directory inodes that they are associated with. (This
was my first stab at it).

My question is about data preservation from inside a FS... I want to
preserve the contents of my queue in case of a crash. When mount is
called I want to scan this list and rebuild the queues in memory. Is it
possible to write data out to a persistent file from within the system?
Would using the module parameter approach be a good way to go? . . . But
from what I understand it wouldn't necessarily export the data if the
system hangs and the module can't be removed.

If anyone can help, has ideas, or some pointers, I would be very
grateful.

Thank You so much!
