Hi Abhijit,
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.
The function "get_sb()" is still present in security/inode.c in kernel 2.6.39. Only the function pointer of get_sb() has been removed from
The name they have kept is the same in security/inode.c but you can compare the prototype to earlier kernel versions. They will be different. Also its assigned to mount function pointer field of struct file_system_type.
struct file_system_type in /include/linux/fs.h.
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.
