Re: [RFC][PATCH] jobfs - new virtual filesystem for job kernel/userinterface

I'd have to second Robin's sentiments. IMHO there should be a very strong reason to have this type of information in a new filesystem as this type of proliferation is counterproductive.

I am looking for your comments on the attached draft, it is the job patch for 2.6.9. I have posted job patch for older kernel before, but in this patch
I have replaced the /proc/job binary ioctl calls with a new small virtual filesystem (jobfs).

Job uses the hook provided by PAGG (Process Aggregates). A job is a group
related processes all descended from a point of entry process and identified
by a unique job identifier (jid). You can find the general information
about PAGG and Job at

I will very much appreciate your comments, suggestions and criticisms
on this new filesystem design and implementation as the job kernel/user
communication interface. The patch is still a draft.

Thank you!

I maintain my position that this belongs in /proc.

Why not have a structure something like:

/proc/<pid>/job -> ../jobs/<jid>
/proc/jobs/<jid>/<pid> -> ../../<pid>

What other information is really necessary from userland?
