issue of ext3_file_write function & remote shares
 

The "ext3_file_write" function in the file "/usr/src/linux-source/fs/ext3/file.c" is called whenever a file is accessed/modified.
Now, i have inserted a simple printk(to know that the function has been called, just for debugging) and some more code of mine in it immediately after declaration/initialization of variables. When a local file is accessed, this printk as well the other code is executed successfully. But when i export a share and mount it remotely and do some operations like writing to a file in it, neither my code nor even the simple printk(which is without any conditions) is executed.
And after this takes place, it doesnt even work locally.
I'm unable to find any solution.
Any help will be welcome.
