Hi list,<br>
It seems that the support for get_sb function is removed from
kernel 2.6.39 onwards. My code which is working till 2.6.38 series
is failing with new kernels.<br>
<br>
I tried finding out but there isnt anything mentioned. So if this
function itself is removed then how kernel is going to find out
the superblock and use it?<br>
<br>
Are we supposed to use the mount function provided? This is what i
got from one of the kernel patch email.<br>

I have modified the code to use the mount function and its working
correctly. There is one more change I noticed for struct
address_space_operations: The sync_page is removed.<br>
<br>
The code is working now.<br>
