Description of problem:
On 2.4.21 based kernels, /proc/pid doesn't include the consolidated resource 
utilization of the threads it has created.

On 2.4.21 based kernels /proc has got hidden directories which has got the 
thread related statistics.
1) /proc/pid reflects resource usage of the process
2) /proc/.pid  (I Was referring to this as a thread ID). Kernel stores thread 
resource utilization under this directory.

The resource utilization (say cpu utilization) statistics under /proc/pid 
doesn't include resource utilization of threads which that process has created.

 I have checked with 'linux-kernel.org' group, they have replied 
that this is a vendor specific issue. I would like to know if this has been 
already fixed in later versions of the kernel.


Version-Release number of selected component (if applicable):
Linux 2.4.21-4.EL

How reproducible:
Run a multi threaded process and check CPU/memory/disk utilization of process 
and we can see that the statistics do not include the CPU/memory/disk 
utilization of the threads it has created.

Steps to Reproduce:
1. Run a process which creates threads.
2. Check the resource utilization provided under /proc/pid
3. Statistics under /proc/pid doesn't reflect /proc/.<tid>
  
Actual results:
Statistics under /proc/pid don't include thread resource utilization of the 
threads it has created.


Expected results:
Statistics under /proc/pid should include thread resource utilization also.


Additional info:
Assume we have a process with pid = 1234
And this process creates two threads with thread IDs 1235 & 1236.
We have three entries
 a)  /proc/1234
 b) /proc/.1235
 c) /proc/.1236
    The statistics under /proc/1234 don't include resource utilization of 
threads 1235 & 1236.
