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>

+ ->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(...).

<br>NOTE : - change is only in one parameter of type struct vfsmount which is basically removed from this function pointer.<br><br>Regards,<br>Rohan Puri<br></div></div><br>
