A question about proc file system

[Yangbin (Robin)]

Hi all:

	I write a kernel module which make a dir and create a file in proc file system. 
I use proc_mkdir() and create_proc_entry() in init and use remove_proc_entry() in exit.
Now I got a problem during my test:
1. open terminal A, insmod and cd into the dir the module created in proc
2. open terminal B. rmmod and insmod angain.
Then I cannot see the file which should be created by the module, unless terminal A quit the dir.

This will be ok with regale file system like ext3, one teminal's operation will not affert others.
Is this a bug or not?

Regards
Robin
