Questions about pseudo plugins

Questions about pseudo plugins

[Yoanis Gil Delgado]

Hi there:
I've been working on the versioning plugin.
I will like to know how can i add a pseudo file to a pseudo directory, 
dynamically. I mean whenever i detect a new version i want to create a 
pseudo file under /file.txt/versioning/version/s pseudo directory.
Another question is about how can I iterate over directories pseudo files.
For example how i can iterate over the files under 
/file.txt/versioning/version/s (remember the files under this directory 
are pseudo files which are generated dynamically).
I know there is a way to add static pseudo files and directories, by 
adding them to pseudo_plugins array. Perhaps using the linkage field 
from pseudo_plugin. I've some more questions but i will come later with 
them.
By the way I found this in the patch for kernel 2.6.15:
    The function init_pseudo receives a _/const char* name  /_which is 
never used.
That's all for now. Thanks a lot .............. yoanis

IFAIK you need to define lookup and readdir methods for your pseudo 
plugins.

Unfortunately it is very low level API for exporting your dynamic 
structures.  Some API like procfs/sysctl would be much better but 
reiser4 does not have it yet.
