Description Jose Plans 2006-07-27 11:07:11 UTC 
Description of problem:

  Even if that is the wrong thing to do. Mounting N times the same share on the
same mount point produces N allocations of N smbmount daemons.
 
   % mount -t smbfs //host/share /mnt/smbfs
   % mount -t smbfs //host/share /mnt/smbfs
   % mount -t smbfs //host/share /mnt/smbfs
   % mount -t smbfs //host/share /mnt/smbfs

  This will show up as 4 processes with about the equal amount of memory allocated. 

Version-Release number of selected component (if applicable):
samba-client-3.0.9-1.3E.9

How reproducible:
Always.

Steps to Reproduce:
1. mount -t smbfs several times from same share to same mount point.
  
Actual results:
several deamons are used for a single ones task.

Expected results:
Only one daemon as CIFS (kernel thread in this case) performing the operation.

Additional info:
I'm not sure if that is by design tho, but at least it shouldn't allocate memory
for each smbmnt operation.
