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.
+ ->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
