Hi Vladimir,

By current limit, are you pertaining to ReiserFS (v3.x) or Reiser4 ?

Hi All,

It is pertaining to Reiser4 

On Reiser4 the limit is 2^32 where as on ReiserFS (v3.x) the limit is
64,536 ( not sure)

I guess you mean reiserfs 3.6 and reiser4, or does it also apply to 
reiserfs 3.5?

this also applies to 3.5. But for 3.5 number of directory links does not
get reported correctly: 1 is reported for directories which have more
than 64535 subdirectories.

Hello,
 
Am a newbie to ReisferFS / Reiser4. 
 
I've been searching the archives and Google for a definite answer as to
what the maximum number of subdirectories under a directory is. A Dec,
2003 article ( http://everything2.com/index.pl?node_id=510028 ) says
it's 64,536. Is this still true ?
 
If not, then what is the current limit for both ReiserFS and Reiser4 ?
 
Regards,
Danny
