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>

+ ->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(...).

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