Hi list,
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.

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?

Are we supposed to use the mount function provided? This is what i got 
from one of the kernel patch email.

+[mandatory]
+	->get_sb() is gone.  Switch to use of ->mount().  Typically it's just
+a matter of switching from calling get_sb_... to mount_... and changing the
+function type.  If you were doing it manually, just switch from setting ->mnt_root
+to some pointer to returning that pointer.  On errors return ERR_PTR(...).
diff --git a/Documentation/filesystems/vfs.txt b/Documentation/filesystems/vfs.txt
It looks like there are other changes related to Pages are also done.

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.

The code is working now.
