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.

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.

Hi Abhijit,
Yes you have to make use of mount function pointer in the
struct file_system_type.
NOTE : - change is only in one parameter of type struct
vfsmount which is basically removed from this function
pointer.

Thanks Rohan. Yes, i have made the changes and things are looking
good. struct address_space_operation's sync_page is also removed.
