[announce] /dev/atomicps

[Borislav Deianov]

Hi,

Last week I posted an idea for an atomic ps that doesn't use /proc. I
now have a more complete implementation. Thanks to Albert Cahalan and
Werner Almesberger for comments and suggestions. Here is the blurb:

This driver allows you to take atomic snapshots of all the data
normally found in /proc/<pid>/ (except command line arguments and
environment). It has the following advantages over /proc:

 - smaller memory footprint, thus more suitable for embedded systems; 
 - requires only a few system calls to read all the data, thus faster; 
 - gives a consistent view of the processes on the system even during 
heavy process activity. 

Kernel patch and a minimal ps implementation (based on code from procps)
can be found at: http://bkernel.sourceforge.net/

Not yet done:

- data and process selection flags (like in procps)
- mmap support

Best wishes,
Borislav
