Hi Arpitha,
Thank you for the patch! Perhaps something to improve:

All warnings (new ones prefixed by >>):
In file included from fs/ext4/inode-test.c:7: fs/ext4/inode-test.c: In function 'ext4_inode_gen_params':

So this means we probably want to make the param_value, and the return and prev types of the generator "const void*".
Thanks, -- Marco
